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 solution set of a disjunction is the union of the solution sets of the individual inequalities. A convenient way to graph a disjunction is to graph each individual inequality above the number line, then move them both onto the actual number line

Explanation:
The detailed steps and appropriate derivation is as shown in the attached file.
Answer:
2.136 N-m
Explanation:
From the question,
Applying,
Toque = FL...................... Equation 1
Where F = Force applied to the the ball, L = Length of the forearm
From newton's second law of motion,
F = m(v-u)/t................. Equation 2
Where m = mass of the ball, v = final velocity of the ball, u = initial velocity of the ball, t = time.
Given: m = 0.140 kg, u = 0 m/s (from rest), v = 24 m/s, t = 0.425 s
Substitute into equation 2
F = 0.140(24-0)/0.425
F = 7.91 N.
Also Given: L = 0.270 m
Substitute into equation 1
Torque = 7.91×0.270
Torque = 2.136 N-m
