Question

a car covers a distance of 300m in 20s. It then accelerates to attain the velocity of 60m/s in next 20 seconds. Then it decelerates for next 10s and attains the velocity of 5m/s.Finally, it continues moving with this velocity for 30s. Find its acceleration,deceleration and total displacement

Answer 1

Acceleration = Final speed - Initial speed/ Total time
Deceleration = Final speed - Initial speed/ Total time
Displacement = Force × distance...now you put the values in it.

Speed = distance / time
