Question

There is a velocity observed from 10m/s to 15m/s . when a force of 300n is applied on a body . calculate the mass of the body ?

Answer 1

Answer:60kg

Explanation:

It is gn that

u=10m/s

v=15m/s

F=300N

We have to find the mass of the object

F=m (v-u)

300=m (15-10)

m=300/5

=60 kg

Answer 2

Mass of the body is 60 kg.

Given:

There is a velocity observed from 10m/s to 15m/s . when a force of 300n is applied on a body .

To find:

Calculate the mass of the body ?

Solution:

First we have to find the acceleration

We have been given

Initial velocity(u) = 10m/s

Final velocity(v) = 15 m/s

We will assume time as 1sec

Acceleration = (v-u) / t

= (15 - 10)/1

= 5 m/s²

Now, we will calculate mass of body

Force = mass * acceleration

300 = Mass * 5

Mass = 300/5

= 60kg

Hence, answer is 60 kg.
