An object moves with uniform speed round a circle. Its acceleration has constant magnitude and constant direction varying magnitude and constant direction constant magnitude and varying direction varying magnitude and varying direction 4. A stone and a feather are dropped from the same height above the earth surface. Ignoring air resistance, which of the following is correct? the stone will reach the ground first the feather will be blown away by the wind while the stone will drop steadily the stone and feather will both reach the ground at the same time the feather will reach the ground first 5. A train with an initial velocity of 20m/s is subjected to a uniform deceleration of 2m/s². The time required to bring the train to a complete halt is 10s 5s 20s 40s 6. Which of the following statements is true of a body which is moving in a straight line with uniform acceleration? The velocity of the body must always be zero when the body stops accelerating is the product of the distance travelled and time is also uniform will increase with time in the direction of the acceleration is equal to the quotient of distance travelled and time 7. A body travels from rest and accelerates uniformly to a speed of 120km/hr in 10 seconds. What is the distance covered? 1000km 6km 600km 60km 1/6km 8. A body falls freely under gravity (g = 9.8m/s²) from a height of 40m onto the top of a platform 0.8m above the ground. Its velocity on reaching the platform is 78.4m/s 784m/s 39.2m/s 80m/s 27.7m/s 9. When a ball rolls on a smooth level ground, the motion of its center is random oscillatory translational rotational 10. A car moves with an initial velocity of 25m/s and reaches a velocity of 45m/s in 10s. What is the acceleration of the car? 25m/s² 20m/s² 2m/s² 5m/s² 11. If a car starts from rest and moves with a uniform acceleration of 10m/s² for 10s. The distance it covers in the last one second of its motion is 95m 905m 500m 100m 1000m 12. A ball is thrown vertically upwards and returns to the thrower after 6s.Calculate the maximum height attained.(Take g = 10m/s²) 135m 45m 150m 90m 180m 13. If a body moves with a constant speed and at the same time undergoes an acceleration, its motion is said to be rectilinear oscillatory circular rotational 14. A mango fruit drops from a branch 10m above the ground. Just before hitting the ground, its velocity is 10√2m/s 10m/s 5√2m/s 200m/s 100m/s 15. During the same interval, it is observed that a train travels the same distance as does a lorry. The two vehicles therefore have the same initial velocity uniform acceleration average speed instantaneous velocity average velocity 16. The motion of a moving skin of a talking drum can rightly be described as translational random transitory oscillatory rotational 17. A car moving with a speed of 90km/hr was brought uniformly to rest by the application of the brakes in 10s.How far did the car travel after the brakes were applied? 250m 15km 150m 125m 25km 18. A moving object has a uniform acceleration. Its velocity increases by equal amounts in equal time displacement increases at a constant rate speed is directly proportional to time velocity varies inversely with time 19. From the top of the Eiffel tower, a rubber ball and a piece of iron rod were dropped to the ground. Which of the following is true? (neglect air resistance) under high temperature condition, the iron rod will first reach the ground both objects will reach the ground at the same time the iron rod will first reach the ground the rubber ball will first reach the ground 20. A ball is dropped from a height of 20m and rebounds with a velocity which is 3/4 of the velocity with which it hits the ground. What is the time interval between the first and the second bounces? 6.0s 3.0s 0.5s 2.0s 1.5s 21. A boy moving with a velocity of 4m/s is brought to rest by a constant force after traveling 20m.Calculate the retardation. 5.0m/s² 0.4m/s² 2.5m/s² 0.2m/s² 0.1m/s² 22. A body starts from rest and moves with uniform acceleration of 6m/s².What distance does it cover in the third second ? 18m 15m 30m 27m 35m 23. A car traveling at 20m/s is brought to rest with a constant deceleration of 10m/s².Calculate the distance traveled. 10m 200m 400m 20m 24. An apple fruit is dropped to the ground from the top a tree 45m tall. How long does it take to reach the ground? (Take g = 10m/s²) 9s 4.5s 3s 6s 7.5s 25. Which of the following types of motion are oscillatory?I. a diving board when used by a diverII. the motion of the balance wheel of a wrist watchIII. the motion of turn-table of a record playerIV. the motion of the center of a coin as it rolls down on an inclined planeV. the motion of a needle of a d.c ammeter into which a low a.c current is passed. II, III & IV only III, IV & V only I, II & III only I, II & V only I & II only 1 out of 25 Time is Up! Time's up
