5. A body of mass 5kg is moving with velocity of 10ms-1. Find the force required to
stop it in 2s:
B. 15N
A. 5N
D. 30N
C. 25N
​

Answer 1

Answer:

c is correct option

Step-by-step explanation:

v=0

u=10m/s

mass =5kg

t=2s

v=u+at

0=10+a*2

-10=2a

a=-5 m/s²

as F=ma

       =5*(-5)

       = -25 N (-ive sign indicate opposing force)
