Question

a car starts from rest and move with uniform acceleration 0.5ms .after 30 sec find the velocity of car and distance covered solve question

Answer 1

we know,
v = u + at. (here, u=0)
or, v = 0.5×30=15m/s
and the distance covered by the car is
x = 1/2 at^2
or, x = 1/2 × 0.5×30×30
or, x = 450 m
