A cyclist is travelling at 15 m `s^(-1)` . She applies brakes so that she does not collide with a wall 18 m away. What deceleration must she have ?

A cylist travelling at 10m/s applies brakes and stops in 25m m. The graph shows the magnitude of the braking force versus the distance travelled. What is the total mass of bike and cyelist?

A car is traveling at 7.0 m/s when the driver applies the brakes. The car moves 1.5 m before it comes to a complete stop. It the car had been moving at 14 m/s, how far would it have continued to move after the brakes were applied ? Assume the braking force is constant .

A driver travelling at 90 kph applied the brakes for 5 s. If the braking acceleration was 2 m//s^(2) , what was her final speed ?

A car weighing 1000 kg is travelling at the speed of 15ms^(-1) . It decelerated due to brakes applied and stops after covering a distance of 25 m. Find the force exerted by the brakes and the work done by the brakes.

Two cars A and B travelling with speed 20m/s and 10m/s respectively applied brakes, so that A comes to rest in 15 second and B in 7.5s. From the graph determine which of the two cars travelled further after brakes were applied and by how much distance it travelled?

A car is moving with a velocity 20 "m s"^(-1) . The brakes are applied to retard it at a rate of 2 "m s"^2 . What will be the velocity after 5 s of applying the brakes?

A car is moving with a velocity 20 m s^(-1) . The brakes are applied to retard it at a rate of 2 m s^(-2) . What will be the velocity after 5 s of applying the brakes ?.
