Question

4. Velocity of a body of mass 20 kg decreases from 20 m/s in a distance of 200
m. Force on a body is .......​

Answer 1

Answer:

The equation of motion is given as,

v

2

=u

2

+2as

(5)

2

=(20)

2

+2×a×100

a=−1.875m/s

2

The force is given as,

F=ma

F=20×(−1.875)

F=−37.5N

Thus, the force on the body is −37.5N
