Conservation of Momentum

Applied Mechanics Velocity

A 1 kg object is dropped from the horizontal while attached to a string 80 cm long, tied at the same height as the object. When the string is vertical after the object is dropped, the object strikes a 2 kg block on a frictionless horizontal surface. The impact is 100% elastic. What will be the velocities of both objects

Calculating velocity in elastic collisions.

A ball of mass m1 = 31.00 grams moving at 15.20 m/s collides head-on with a stationary ball of mass m2 = 116.00 grams. The collision is elastic. What is the velocity of the first ball immediately after the collision?

Working with conservation of momentum and collisions.

On a frictionless ice, a block whose mass is A= 6 kg is sliding toward +x with a velocity VA= 8 m/sec, when it collides in a non-elastic collision with a block of mass B= 4 kg moving at an unknown velocity VB. After collision the joined blocks move with momentum P= 84 i + 48 j where i and j are unit vectors. a. Find PB the or

The Conservation of Momentum

N men, each with mass, m, stand on a railway flatcar of mass, M. They jump off one end of the flatcar with velocity u relative to the car. The car rolls in the opposite direction without friction. a) What is the final velocity of the flatcar if all the men jump at the same time? b) What is the final velocity of the flat

Calculations on an Exploding Projectiles

An instrument carrying projectile accidentally explodes at the top of its trajectory. The horizontal distance between the launch point and the point of explosion is L. The projectile breaks into pieces which fly apart horizonally. The larger piece has three times the mass of the smaller piece. To the surprise of the scientist in
