Question

If Siobhan hits a 0.25 kg volleyball with 0.5 N of force, what is the acceleration of the ball?

Answer 1

Answer:

2N/Kg.

Explanation:

We know , force = mass x acceleration.

force = 0.5

mass = 0.25 kg.

acceleration = force / mass

= 0.5 / 0.25

= 2 N/kg.

Answer 2

Given,

Mass of the volleyball = m = 0.25 Kg = 250 grams

Siobhan hits the volleyball with a force = F = 0.5 N

To find,

The acceleration of the ball.

Solution,

We can simply solve this numerical problem by using the following process:

Let us assume that the acceleration of the volleyball is "a" meters per second square.

Newton's second law states that;

" The force F acting on a body is equal to the product of mass m of the body and the acceleration a of its center of mass, i.e. F = ma "

Now,

Force acting on the volleyball = mass of the volleyball x acceleration of the ball

=> F = m x a

=> 0.5 N = 0.25 kg x a

=> a = (0.5 ÷ 0.25) meters per second square

=> a = 2 meters per second square = 2 m sec^-2

Hence, the acceleration of the ball is 2 meters per second square.
