Question

A body of mass 2kg moves from rest with uniform acceleration and travels 270m in 3 seconds. What will be the velocity after 10 seconds after it starts. *

Answer 1

Answer:

600 m/s

Explanation:

u=0,s=270m,t=3s

s=ut+21at2

270=0×3+21×a×32

a=60 m/s2

Now putting the value of a in v=u+at,

Velocity after t=10s is given by

v=0+60×10=600 m/s
