Question

A soccer ball (m = 5 kg) travels to the right with an initial velocity of 10 m/s. The soccer ball hits a stationary basketball (M = 15 kg). They undergo a perfectly elastic collision.

a) What is the velocity after the collision of the soccer ball

b) What is the velocity after the collision of the basketball?

Answer #1

A 0.40 kg soccer ball is moving to the right with speed of 25m/s
when it collides with a 0.60 kg basketball moving to the left with
speed of 20 m/s. The basketball bounces off with speed of 12 m/s at
an angle of 32.0° relative to its initial path as shown if the
figure.
At what angle, φ, relative to its original path does the soccer
ball move after the collision?
What is the speed of the soccer ball...
