Question

the body of mass 2 kg is at rest what should be the magnitude of force which will make body move with a speed of 30 metre per second at the end of 1 second​

Answer 1

Answer:

Given :-

m = 2 kg

u = 0 m/s

v = 30 m/s

t = 1

a = 30 m/s²

f = ma = 30 *2 = 60N

Answer 2

Answer:

60 N

Explanation:

• You first need to take out the acceleration of the block from rest using the formula v=u+at.
• Then you need to use the formula F=ma and insert the data.
• You will get the required answer.
