A car of mass `=m=1000 kg` is moving with constant speed `v=100 m//s` on a parabolic shaped bridge AFOE of span force applied by the bridge on the car when he car is at point E, is:

A car of mass 1000 kg is moving with a certain speed when a constant braking force 1000 N acts on it for 5s and the speed of the car reduces to half its original speed. Find the further time required to stop the car if the same constant force acts.

I here is a parabolic shaped bridge across the river of width 10 meter.The highest point of the bridge is 4 meter above the level of bank.A car of mass 72kg is crossing the bridge at a constant speed of 5m/s . Find the force (in Newton) exerted on the bridge by car when it is at the highest point P of the bridge. (take g=10m/s^(2))

A car of mass m moves with a constant speed upsilon over (a) horizontal flat surface (b) convex bridge (c) concave bridge What force is exerted by the car on the bridge as it passes the middle point of bridge Radius of curvature of bridge is R .

A car of mass 1000 kg is moving with a speed of 40 ms^(-1) on a circular path of radius 400m. If its speed is increasing at the rate of 3ms^(-2) the total force acting on the car is
