Question

velocity of an object of mass 5kg increases from 5m/s to 10m/s on applying a force continuously for 2s. Find out the force applied? ​

Answer 1

Answer:

12.5 Newton

Explanation:

First we have to find acceleration

a = ( v - u)/t

= (10 - 5)/2

= 5/2

= 2.5

Now we will find force,

F = ma

= 5 × 2.5

= 12.5

Hope it helps

Answer 2

Answer:

given

mass=5kg

time1=2s

Initial velocity u=5m/s

Final velocity v=10m/s

Let the Force be F

f=v-u/t

5-10/2=7.5m/s
