Question

Q5 A car starts from rest, acquires a velocity of 72 km/hr in 10 sec. Find the acceleration and force applied on the body of 1.5 metric ton.

Answer 1

Explanation:

u=0

v=72km/h=72×5/18=20m/s

t=10s

a=v-u/t=20-0/10=2m/s²

mass=1.5 metric ton =1500kg

1 METRIC TON=1000Kg

F=ma=1500×2=3000N
