Question

A 7.5 force is applied to a football, causing an acceleration of 15 m/s2. Calculate the mass

Answer 1

The mass of the football is 500 g.

Step-by-step explanation:

Given,

F = 7.5 N

Acceleration (f) = 15 m/s²

To find the mass (m) of the ball.

Formula

F = mf

According to the problem,

m×15 = 7.5

or, m = $\frac{7.5}{15}$ = 0.5 kg = 500 g

Hence,

The mass of the football is 500 g.

Answer 2

Step-by-step explanation:

We know that we have the formula that F = ma

Given

Force (F) = 7.5 N

Acceleration (a) = 15 m/s²

Mass (m) = ?

Now

F = ma

7.5 = m * 15

m = 7.5/ 15

Mass = 0.5 kg
