1. A car is moving at a constant velocity of 20 m s−1. The engine provides a forward thrust of 1500 N. What is the magnitude of the total resistive force (air resistance and friction) acting on the car?
2. An object is subjected to two forces, 8 N and 6 N, acting in opposite directions along the same line. What is the magnitude and direction of the resultant force?
3. A free-body diagram for a book resting on a horizontal table would show which of the following forces acting on the book?
4. Two identical springs are arranged in parallel and a load is hung from them. How does the extension of this system compare to the extension of a single spring with the same load?
5. According to Newton's Second Law, if a non-zero resultant force acts on an object, what is the state of the objects motion?
6. A block of weight 50 N is at rest on a smooth inclined plane at an angle of 40∘ to the horizontal. A frictional force, F R, prevents it from sliding down. What is the magnitude of this frictional force?
7. The graph of force (F) versus extension (x) for a spring is plotted. What does the gradient of this graph represent?
8. Which of the following describes the property of 'elasticity'?
9. The elastic potential energy stored in a spring is 0.4 J when it is extended by 5 cm. What is the force required to cause this extension?
10. Which of the following factors does NOT affect the spring constant of a coil spring?
