A ball moving with a speed of 9m.s strikes an identical ball at rest, such that direction fo eahc ball makes an angle `30^@` with the original line. Find the speed of two ball after collision.

A ball of mass m moving with a constant velocity strikes against a ball of same mass at rest.If e is the co-efficient if restitution what will be the ratio of velocity of two balls after collision?

A ball moving with momentum of 5kgms^-1 strikes against a wall at an angle 45^@ and is reflected at the same angle. Calculate the change in momentum.

When is a collision said to be a perfectly inelastic? A mass is moving with speed v collides inelastically with another identical mass at rest. After collision, the first mass moves with velocity frac(nu)(sqrt 3) in a direction perpendicular to the initial direction of motion. Find the speed of the second mass after collision.

Two identical ball bearings in contact with each other and resting on a frictionless table are hit head-on by another ball bearing of the same mass moving initially with a speed VL If the collision is elastic, which of the following figure is a possible result after collision?

A molecule in a gas container hits a horizontal wall with speed 200 m s-^1 and angle 30^@ with the normal, and rebounds with the same speed. Is momentum conserved in the collision? Is the collision elastic or inelastic?

A proton moving with velocity (10^7) m/s to enters a magnetic field of 1.5 T making an angle 30° with the direction of the field. Find the radius of the helical path and its frequency of rotational motion

Work Problem related to speed, distance and time Two places A and B are at distance 160km . Two cars starting form tha same place and moving in the same direction meet after eight hours. Again moving in the oppoosite directions from A to B. The cars meet each other after one hour. Find the speed of the cars.

A police van moving on a highway with a speed of 30 km h_ 1 fires a bullet at a thief’s car speeding away in the same direction with a speed of 192 km h^-1 . If the muzzle speed of the bullet is 150 m s^1 with what speed does the bullet hit the thief’s car ? (Note: Obtain that speed which is relevant for damaging the thief’s car).

A proton enters a magnetic field of flux density 1.5Wb/m^2 with a speed of 2×10^7 m/s at angle of 30^o with the field. Find the force on the proton .
