... Here’s what we can say: at the top of the trajectory, the vertical component of the velocity is zero. Throughout (prior to the explosion), the horizontal component of the velocity is 20cos60° = 10 m/s. Due to the conservation of momentum, if one fragment falls to a dead stop, the other must go at t ...

... A 2.0 kg ball, A, is moving at a velocity of 5.0 m/s. It collides with a stationary ball, B, also of mass 2.0 kg. After the collision, ball A moves off in a direction 300 to the left of its original direction. Ball B moves off in a direction 900 to the right of ball A’s final direction. a. Draw a v ...
