1. This car is travelling on the open road at a constant speed of 28ms–1. Part of the road forms the arc of a circle of radius 80m. The mass of the car and its four occupants 1357kg. 1 Which arrow shows the direction of the resultant force acting on the car as it travels around the corner at constant speed? What provides the resultant force? 2 Calculate the value of the resultant force. Give your answer to the correct number of significant figures. 3 F = ma F = m F = -kx b a c d
