A bus is travelling at 15 m/s. It slows down steadily and stops at a bus stop. It takes 6.0 s to stop.
Use the equation: acceleration=change in velocitytime\text{acceleration} = \dfrac{\text{change in velocity}}{\text{time}}acceleration=timechange in velocity
Calculate the deceleration of the bus.
The bus then pulls away from the bus stop. It accelerates from rest at 1.2 m/s2 for 10 s.
Calculate the velocity of the bus after 10 s.
A cyclist speeds up from 2.0 m/s to 8.0 m/s. Her acceleration is 0.75 m/s2.
Calculate the time taken.
