Questions
If the coefficient of restitution between a ball and the floor is 0.5, what is the percentage loss of energy on each rebounding of a ball dropped from a height ?
detailed solution
Correct option is D
we know that e=v1−0v−0=v1v or 0⋅5=v1/v or v1=0⋅5V Percentage loss of K.E' is given bY 12mv2−12mv1212mv2×100=v2−(0⋅5v)2v2×100 =34×100=75%Talk to our academic expert!
