10, What is the minimum height h för which the block will reach point A on the loop without leaving the track? Correct, computer get8: 5.00E+01 m 11 A small block of mass m, which weighs 7.154 N, is hit so that it slides up a frictionless inclined plane. The surface of the inclined plane is at an angle 0 relative to the horizontal. Just after the mass is hit it has a speed of 12.80 m/s. The mass slides up the incline and travels a distance D along the incline before starting to slide back down. Find the work done by gravity on the block from its starting position up the ramp over the distance D. (Use g = 9.80 m/s?.) Answer: Submit All Answers It takes a minimum distance of 48.96 m to stop a car moving at 12.0 m/s by applying the brakes (without locking the wheels). Assume that the same frictional forces apply and find the minimum stopping distance when the car is moving at 27.0 m/s. 12.
