Two river balls undergo an elastic collision. Call 1 has a mass of 10 kg and an initial velocity of 5 m/s in the positive x direction. Ball 2 has a mass of 10kg and is stationary. What is the final velocity of ball 1, or v 1f?
Added by Taylor S.
Step 1
First, we need to find the initial momentum of the system. Since ball 2 is stationary, its initial momentum is 0. The initial momentum of ball 1 is given by the product of its mass and initial velocity: p1_initial = m1 * v1_initial = 10 kg * 5 m/s = 50 kg*m/s. Show more…

Two bouncy balls experience an elastic head on collision: Ball 1, whose mass is m1=1.4 kg and whose initial velocity is 15 m/s, collides with ball 2, whose mass is m2=0.9 kg and initially at rest What is the final speed of ball 2 after the collision?

Two balls collide in a perfectly elastic collision. Ball 1 has mass 4.0 kg and is initially travelling at a velocity of 5.5 m/s [right]. It collides head-on with stationary ball 2 with mass 6.0 kg. Determine the final velocities of both balls.

Ball 1 of mass 1.5 kg is traveling towards Ball 2 of mass 1.1 kg. Ball 2 is initially at rest. The balls collide elastically. After the collision, Ball 1 has a velocity of 0.545 m/s and Ball 2 has a velocity of 4.03 m/s (they are both traveling in the same direction after the collision). What was the initial velocity of Ball 1 before the collision?
