A car is travelling along a flyover bridge which is a part of vertical circle of radius `10m`. At the highest point of it the normal reaction on the car is half of it’s weight, the speed of car is

A car is moving up with uniform speed along a fly over bridge which is part of a vertical circle. The true statement from the following is

A motor car is travelling at 60m//s on a circular road of radius 1200m. It is increasing its speed at the rate of 4m//s^(2) . The acceleration of the car is:

A car moves at a constant speed on a straigh but hilly road. One section has a crest and dip of the 250m radius. (a) As the car passes over the crest the normal force on the car is half the 16kN weight of the car. What will the noraml force on the car its passes through th ebottom of the dip? (b) What is the greatest speed at which the car can move without leaving the road at the top of the hill ? (c) Moving at a speed found in part (b) what will be the normal force on the car as it moves through the bottom of the dip? (Take, g=10m//s^(2))
