WebPhysics. Physics questions and answers. a) What is the speed, in meters per second, of the roller coaster at the top of the loop if the radius of curvature there is 11 m and the downward acceleration of the car is 1.9g? Note that g here is the acceleration due to gravity. b) The beginning of this roller coaster is at the top of a high hill. WebIf the acceleration is a= m/s² then a net force= Newtons is required to accelerate the mass. This requires a support force of F= Newtons. Note that the support force is equal to the weight only if the acceleration is zero, and that if the acceleration is negative (downward), the support force is less than the weight.
