Question

What force is needed to accelerate a 25 g ball object at 5 cm/s2

Answer 1

Force = mass×accelaration

F = 25×5

therefore the force is 125 newtons

Answer 2

The answer is 1.25 × 10⁻³ N

GIVEN

Mass of ball = 25 grams

Acceleration = 5cm/s²

TO FIND

Force needed

SOLUTION

We can simply solve the above problem as follows;

It is given that mass of ball = 25 grams = 25/1000 = 0.025 kg

Acceleration of the ball = 5cm/s² = 0.05 m/s²

From Newton's second law of motion

F = ma

Where,

F = force exerted on the object

m = mass of the body

a = acceleration

Therefore,

F = 0.025 × 0.05

= 0.00125

= 1.25 × 10⁻³ N

Hence, The answer is 1.25 × 10⁻³ N
