Complete Question

A 10 kg medicine ball is thrown at a velocity of 15 km/hr ( m/s) to a 50 kg skater who is at rest on the ice. The skater catches the ball and subsequently slides with the ball across the  ice.

Calculate the kinetic energy after collision(in joules).

Explanation:

From the question we are told that:

Mass of ball

Speed

Mass of Skater

Generally the equation for conservation of momentum is mathematically given by

Generally the equation for  Kinetic energy is mathematically given by

Therefore kinetic energy K.E after collision is given as

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
