Answer 1

To find the force exerted on the body, we can use Newton's second law of motion. Substituting the given values, we find that the force exerted on the body is 3 N.

Step-by-step explanation:

To find the force exerted on the body, we can use Newton's second law of motion, which states that force is equal to mass times acceleration. In this case, acceleration can be calculated using the formula:

a = (v - u) / t

Substituting the given values, we get:

• a = (5 m/s - 0 m/s) / 25 s = 0.2 m/s²

Now, we can use the formula for force:

F = m * a

Substituting the values, we get:

• F = 15 kg * 0.2 m/s² = 3 N

Therefore, the force exerted on the body when m = 15 kg, u = 0 m/s, v = 5 m/s, and t = 25 s is 3 N.
