A car of mass M moves with a constant speed `v` over a concave bridge. What force is exerted by the car on the bridge in the case, as it passes the middle point of the bridge ? Take radius of curvature of the bridge in this case as r.

A car of mass 1000 kg moving with a velocity of 36 km/h comes to rest in 5 seconds. What is the force exerted on the car?

A car when passes through a convex bridge exert a force on it which is equal to :

What provides the centripetal force in the following cases car taking a turn?

A wire connected in the left gap of a meter bridge balance a 10Omega r esistance in the right gap to a point, which divides the bridge wire in the ratio 3:2. If the length of the wire is 1m. Calculate the length of one ohm wire.

A train passes over a 200 m long bridge in 10s. The length of the train is 100 m. The speed of the train is

A car of mass m starts from rest and acquires a velocity along east vec v = vhati (v>0) in two seconds. Assuming the car moves with uniform acceleration, the force exerted on the car is

A train 100 m long is moving with a velocity of 60 kmh^-1 . Find the time it takes to cross the bridge 1 km long.

If the distribution of weight is uniform, then the rope of the suspended bridge takes the form of parabola.The height of the supporting towers is 20m, the distance between these towers is 150m and the height of the lowest point of the rope from the road is 3m. Find the equation of the parabolic shape of the rope considering the floor of the parabolic shape of the rope considering the floor of the bridge as X-axis and the axis of the parabola as Y-axis. Find the height of that tower which supports the rope and is at a distance of 30 m from the centre of the road.
