A car is moving at a speed of `72 km//h`. The diamter of its whells is `0.5 m`. If the wheels are stopped in `20` rotations by applying brakes, calcualte the angular retardation produced by the brakes.

A car is moving at a speed of 72 km//h . The diameter of its wheels is 0.5 m . If the wheels are stopped in 20 rotations by applying brakes, calcualte the angular retardation produced by the brakes.

A car is moving at a speed of 72 kmh^(-1) . The diameter of its wheel is 0.50m. If the wheels are stopped in 20 rotations by applying brakes, calculate the angular retardation produced by the brakes.

The speed of a moving car is 60kmh^(-1) . The wheels having diameter of 0.60 m are stopped in 10 rotations by applying brakes. What will be the angular retardation produced by brakes?

A bus running at a speed of 18 km/h is stopped in 2.5 seconds by applying brakes. Calculate the retardation produced.

A truck is moving at a speed of 54 km/h. The radius of its wheels is 50 cm. On applying the brakes the wheels stop after 20 rotations. What will be the linear distance travelled by the truck during this? Also find the angular acceleration of the wheels.

A driver is driving a car at a speed of 90km/h. he spots a child standing on his way and decided to apply the brakes but it took him 0.3s to actually apply the brakes. If the retardation produced by the brakes is 10m//s^(2) , calcualtion the total distance covered by car before coming to rest

A car of mass 2400 kg moving with a velocity of 20 m s^(-1) is stopped in 10 seconds on applying brakes Calculate the retardation and the retarding force.

Find the initial velocity of a car which is stopped in 10 seconds by applying brakes. The retardation due to brakes is 2.5 m/ s^(2) .
