Questions
A particle falls from a height h upon a fixed horizontal plane and rebounds. If e is the coefficient of restitution, the total distance travelled before rebounding has stopped is
detailed solution
Correct option is D
Particle falls from height ft then formula for height covered by it in nth rebound is given byhn = he2nwhere e = coefficient of restitution, n = No. of rebound Total distance travelled by particle before rebounding has stopped: H=h+2h1+2h2+2h3+2hn+……=h+2he2+2he4+2he6+2he8+……=h+2he2+e4+e6+e8+……=h+2he21−e2=h1+2e21−e2=h1+e21−e2Talk to our academic expert!
