PPH0075 Physics 1 Chapter 3 ASD 1/ 5 TUTORIAL 3: Dynamics 1. A block of mass 4.0kg rests on a horizontal surface. What horizontal force is required to accelerate the block at 5.0m/s 2 if (a) there is no friction, and (b) if the coefficient of kinetic friction is 0.25? 2. An object of mass 10.0kg is subjected to the following forces: 25.0N due east, 50.0N at an angle of 53.0 o north of east, and 40.0N due west. What is the acceleration of the object? 3. Two blocks are connected by a cord on a horizontal surface (figure1). A force F pulls on the blocks, as shown below. Find the acceleration of the blocks and the tension in the connecting cord if (a) the surface is frictionless, and (b) the coefficient of kinetic friction is 0.20. 4. Traveling at a speed of 58.0 km/h, the driver of an automobile suddenly locks the wheels by a slamming on the brakes. The coefficient of kinetic friction between the tires and the road is 0.720. How far does the car skid before coming to a halt.? Ignore effects of air
