A body covers a distance of 25m in the 5th sec of its motion and 40m in the 8th sec.of its motion. Calc.initial velocity and acceleration.

• Physics -

calculate velocity in the fifth second and the 8th second.

veloicty(t=5)=25m/1sec
velocity(t=8)=40m/s

acceleration=changevelocity/time=15m/s/(3sec)
=5m/s^2
