Question

Velocity of an object changes from 2 m/s to cons in 4 second if the mass of the object is 10kg. Then to how much force will be require to do this? ​

Answer 1

Answer:

Hi .

Good afternoon .

Have a nice afternoon .

Answer 2

Answer:

Mass of the body =10 kg

Initial velocity u=4 m/s

Final velocity v=8 m/s

Time t=2s

a) Momentum before force acts p

1

=m×u=10×4=40kg.m/s

b) Momentum after force acts p

2

=m×v=10×8=80kg.m/s

c) Gain in momentum per second =

2

40

=20kg.m/s

d) Acceleration a=

t

v−u

=

2

8−4

=2m/s

2

Force =m×a=10×2=20 N
