A roller -coaster car a mass of `500 kg` when fully loaded with passengers

a. If the vehicle has a speed of `20.0ms^(-1)` at point what is the force exerted by the track on the car at this point ?
b. What is the maximum speed the vehicle can have point B and still remain on the track?

A roller coaster car has mass of 1300 kg when fully loaded with passengers. As the car passes over the top of a circular hil of radius 20m, its speed is not changing. At the top of the hill, what are the (a) magnitude F_(N) and (b) direction (up or down) of the normal force on the car from the track if the car's speed is v=11m/s? What are (C) F_(N) and (d) the direction if v=14m/s?

A small toy car of mass m slides with negligible friction on a ''loop'' the loop track as shown in Fig.3E.32. The toy car starts from rest at a point H above the level of the lowest point of the track (a) If H = 2R , what normal force is exerted by the track on the toy car at point q?. What are the speed and normal force at point r ? (b) At what height will the ball leave the track and to what maxiumum height will it rise afterwards ? (c) If H = 4R , what is the speed and normal reaction reaction at point s ?

Figure shows the roller coaster track. Each car will start from rest at point A and will roll with negligible friciton. It is important that there should be at least some small positive normal force exerted by the track on the car at all points, otherwise the car would leave the track. With the above fact, the minimum safe value for the radius of curvature at point B is (g=10m//s^(2) :

A car moves with a constant speed on a road. The normal reaction exerted by the road on the car is N_(A) and N_(B) when it is at the points A and B respectively, then
