Question

A force of 0.6 N acting on a body increases its velocity from 5 m/s to 6 m/s in 2s, calculate the mass of body​

Answer 1

Force= 0.6 N

acceleration=v-u/t =6-5/2 =1/2 m/s^2

So,mass=Force/ acceleration

=0.6/0.5

=60/50

=6/5 kg

Answer 2

Answer:

mass of the body is 1.2kg

Explanation:

Given

Initial velocity(u) - 5m/s

Final velocity (v) - 6m/s

time taken - 2 sec

Force (f) - 0.6N

➡️ we will find the acceleration of the body, using first Eq of motion

v=u+at

6=5+ax2

2a=1

a=1/2

a=0.5m/s²

Now,

Force = Mass x acceleration

Mass. = force/acceleration

= 0.6/0.5

=1.2 kg
