How does a bicycle stop when its brakes are applied ?

When brakes are applied on a moving car, the car dips to the front. Why ? [That is try to show that front wheels are more pressed as compared to rear ones when the brakes are applied]. Assume that centre of mass of the car is equidistant from the front and rear wheels.

Stopping distance of vehicles : When brakes are applied to a moving vehicle, the distance it travels before stopping is called stopping distance. It is an important factor for road safety and depends on the initialy velocity (v_(0)) and the braking capacity, or deceleration -a that is caused by the braking. Derive an expression for stopping distance of a vehicle in terms of v_(0) and a .

A motor car is moving with a velocity of 108 km//h and it takes 4 second to stop after the brakes are applied. Calculate the force exerted by the brakes on the motorcar if its mass along with the passenger is 1000 kg .

Brakes are applied to car moving with disengaged engine, bringing it to a halt after 2s Its velocity at the momnet when the breaks are applied if the coefficient of friction between the road and the tyres is 0.4 is .

A wheel of a bicycle is rotating about its axis with an angular velocity of 100 rpm. When the brakes are applied, the wheel comes to rest in 10 s. Calculate the number of revolutions made by the wheel before coming to rest. Assume that the deceleration is constant.

A person is riding a bicycle, and its wheels have an angular velocity of +20.0 rad/s Then, the brakes are applied, and the bike is brought to a uniform stop. During braking, the angular displacement of each wheel is +15.92 rev. How much time does it take for the bike to come to rest?
