Question

| 37.
A body of mass 2 kg is at rest. What should be the magnitude of force which will make the body||
move with a speed of 30 m/s at the end of 1 s?
AT 5 N
B) 25 N
C) 60 N
D) 50 N​

Answer 1

Answer:

ATQ

F=m*a

Or

F=m*v-u/t

F=2*30-0/1

F=60N

Explanation:

u=0( as body is at rest)

and

a=v-u/t

Hope I help you

Answer 2

Answer:

60 N

Explanation:

Acceleration = Change in velocity / Time

From rest to end of 1 second

= (30 - 0) / 1

= 30 m/s²

F = ma

= 2 kg × 30 m/s²

= 60 N
