In collision of the steel ball and the steel plate, the collision is an inelastic collision and there is loss in the kinetic energy.
<h3>What are collisions?</h3>
Collisions occur when two objects that are moving in the same directions or in different direction meet each other and collide.
There are two types of collisions:
- elastic collision - the kinetic energy is conserved
- inelastic collision - there is a loss in kinetic energy
In the collision of the steel ball and the steel plate, there is loss in the kinetic energy of the steel ball which is converted to sound energy.
In conclusion, the collision of the steel and steel plate is an inelastic collision.

Answer:
The 7.0-kg bowling ball with a speed of 6.0 meters per second
Explanation:
Momentum is p=mv
m = mass, v = velocity. (velocity is speed with direction)
1. 0.046-kg golf ball with a speed of 60.0 meters per second.
The mass is 0.046kg , velocty is 60.0
p= mv = 0.046 x 60 = 2.76kg
2. 7.0-kg bowling ball with a speed of 6.0 meters per second
Mass is 7kg, velocity = 6
p=mv = 7 x 6 = 42kg
The 7.0kg bowling ball has more momentum because 42 is greater than 2.76.
