What is the time interval between the first and the second bounces?6.0s3.0s0.5s2.0s1.5s17. When a ball rolls on a smooth level ground, the motion of its center isoscillatoryrotationalrandomtranslational18. During the same interval, it is observed that a train travels the same distance as does a lorry. The two vehicles therefore have the sameaverage velocityinstantaneous velocityinitial velocityaverage speeduniform acceleration19.
