A ball collides at `B` with velocity `10m//s` at `30^(@)` with vertical. There is a flag at `A` and a will at `C`. Collision of ball with groundis perfectly inelastic `(e=0)` and that with wall is elastic `(e=1)`. Given `AB = BC=10 m`. Find the time after which ball will collide with the flag.

Choose the correct answer: A ball collides at B with velocity 10m//s at 30^(@) with vertical. There is a flag at A and a wall at C . Collision of ball with ground is perfectly inelastic (e=0) and that with wall is elastic (e=1) . Given AB = BC=10 m . Find the time after which ball will collide with the flag.

A 10kg ball and a 20kg ball approach each other with velocities 20m//s and 10m//s respectively. What are their velocities after collision, if the collision is perfectly elastic ?

Two balls of equal masses movin with velocities 10m/s and -7m/s respectively collide elatically. There velocities after collision with be

A ball of mass 3 kg collides with a wall with velocity 10 m/sec at an angle of 30° and after collision reflects at the same angle with the same speed. The change in momentum of ball in MKS unit is-

A ball of mass M moving with a velocity v collides perfectly inelastically with another ball of same mass but moving with a velocity v in the opposite direction. After collision

A ball of mass m moving horizontally at a speed v collides with the bob of a simple pendulum at rest. The mass of the bob is also m. If the collision is perfectly inelastic and both balls sticks, the height to which the two balls rise after the collision will be given by:

A ping-pong ball strikes a wall with a velocity of 10 ms^(-1) . If the collision is perfectly elastic, find the velocity if ball after impact

A ping-pong ball strikes a wall with a velocity of 10 ms^(-1) . If the collision is perfectly elastic, find the velocity if ball after impact
