Answer:

3.33 N

Explanation:

First, find the acceleration.

Given:

Δx = 3 m

v₀ = 0 m/s

t = 3 s

Find: a

Δx = v₀ t + ½ at²

3 m = (0 m/s) (3 s) + ½ a (3 s)²

a = ⅔ m/s²

Use Newton's second law to find the force.

F = ma

F = (5 kg) (⅔ m/s²)

F ≈ 3.33 N

Picture a ball traveling at a constant speed around the inside of a circular Structure. is the ball acceleration? Explain why?
baherus [9]
Yes. On a circular path, the direction of motion is constantly changing. Change of direction is acceleration, even at constant speed.
