Answer 2

Calculation of Force

To determine the force acting on the ball, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Given: - Mass of the ball (m) = 250 g = 0.25 kg - Distance traveled (d) = 4 m - Time taken (t) = 2 s

To find the force (F), we need to calculate the acceleration (a) first. We can use the formula for acceleration:

a = (2 * d) / (t^2)

Substituting the given values:

a = (2 * 4) / (2^2) = 8 / 4 = 2 m/s^2

Now, we can calculate the force using Newton's second law:

F = m * a

Substituting the values:

F = 0.25 kg * 2 m/s^2 = 0.5 N

Therefore, the force acting on the ball is 0.5 Newtons.
