Question

(iv) What is the change in kinetic energy of a baseball hit with a force of 6000 N that travels 120 m
across the field?
(a) 6000 J (b) 240 J (c) 120000 J (d) 720000J​

Answer 1

Answer:

Option D: 720000

Step-by-step explanation:

Answer 2

Answer :-

Given -

• Force = 6000 N
• Displacement = 120 m

To Find :-

• Change in kinetic energy

Solution :-

Work - Energy theorem -

Work done by forces acting on the body is equal to the change in kinetic energy of the body.

So, Change in kinetic energy = Work done

Work done = Force × Displacement

= 6000 × 120

= 720,000

Hence,

Change in kinetic energy = 720000 J
