The ball will accelerate at a rate of
Explanation:
We can describe the motion of the ball by using Newton's second law, which states that the net force exerted on an object is equal to the product between the mass of the object and its acceleration:
where
F is the net force
m is the mass
a is the acceleration
In this problem,
F = 14 N is the force exerted on the ball
m = 4.5 kg is the mass of the ball
Solving the equation, we find its acceleration:
So, the ball will accelerate at a rate of .

Answer:
500N/m
Explanation:
Original Length = 20cm
Final length = 22cm
extension = 22 - 20 = 2cm = 0.02m
Force F = 10N
From Hooke's law, F = ke
==> k = F/e = 10/0.02 = 500N/m
