The following two questions deal with a 1000kg car. How high on a hill must an engineless resistance-free car start for its speed at the bottom to be 50m/sec. This car is now on a flat turn of radius 500m and has a static coefficient of friction (ms) of 0.5 with the dry road. Find the maximum speed the car can travel at without skidding off the road (can he make it).
