Question

A constant force is acting on a body of mass 3 kg, changes its momentum
6 kg m/s to 10.5 kg m/s in 25 seconds in a certain direction. What is the
magnitude of force ?​

Answer 1

Answer:

0.18

Explanation:

We have,

m=3kg

u=2m/s

v=3.5m/s

t=25 sec

Now applying the equation: v=u+at

we get, a = v-u/t

On substituting the values,

3.5 - 2/25

We get,

a= 0.06 m/s square

Now in the end, substituting F= m×a

We get,

F= 3× 0.06

F = 0.18 N
