Question

a body having a mass of 5kg moving with a velocity of 20 m/s and reaches a point in 10 sec Find the force on the body​

Answer 1

Answer:

Given,

m=5kg

u=20m/s

F=100N

t=10s

Force, F=ma

a=

m

F

a=

5

100

m/s

2

a=20m/s

2

From 1st equation of motion,

v=u+at

v=20+20×10

v=20+200

v=220m/s

Answer 2

Answer:

10

Explanation:

f = m*v/t

= (5*20)/10
