1. Use a real-life example to explain Newton's First Law of Motion. [An object in motion stays in motion, an object at rest stays at rest]. ( 3 marks) 2. A sprinter runs in a straight line down a pathway for 220m[W] in 12 seconds. What is the sprinter's velocity? (2) 3. A block is being pushed forward from left to right on a flat surface with an applied force of 910N. The force of friction on the block is 30N. The mass of the block is 8.0kg. a) Draw a free body diagram showing the forces acting on the block. (2 marks) b) What is the net force acting on the block (difference between the applied force and the friction force)? (1 mark) c) What is the acceleration of the block? (2 marks)
