Question

A plastic ball falling from a height 4.9 m rebounds number of times. If total time for second collision is 2.4 sec, then coefficient of restitution is 1) 0.3 2) 0.4 3) 0.7 4) 0.6​

Answer 1

Answer:

If total time for second collision is 2.4sec, then coefficient of restitution is. Solution : T=t+2t1=√2hg[1+2e] since tn=en′t.
