Question

A 10 N force applied on a body produces in it an acceleration of 2 ms−2. The mass of the body is what?

Answer 1

Answer:

5 kg

Explanation:

Given :

Force ( F ) = 10 N

Acceleration ( a ) = 2 m / sec^2

We have to find mass of body.

From second law of motion

we have

F = m a

where

F = Net Force

m = mass

a = acceleration

put the value here we get

10 = m × 2

2 m = 10

m = 10 / 2

m = 5 kg

Thus the mass of the body is 5 kg.

Answer 2

Force = 10N

acceleration = 2 ms^-2

well, F = ma

if you don't know

then as we know f = dp/dt

f = m dv/dt

f = ma

So m= f/a

= 10/2

= 5 kg
