Question

The velocity of a body moving with a uniform acceleration 2m/s² is 15 m/s. What would be its velocity after 5s?

Answer 1

acceleration = 2m/s^2
velocity =15m/s


acceleration=velocity/time
then, time = velocity/acceleration
time= 15/2 = 7.5s


velocity = distance / time
then, distance= velocity × time
distance=15×7.5=112.5 m

now, velocity = distance /time=112.5/5=22.5m/s



hope it helped u...if yes plz mark it....
