The variation with time t of the acceleration a of an object is shown.What is the change in velocity of the object from t = 0 to t = 6 s?
- A climber of mass m slides down a vertical rope with an average acceleration a. What is the average frictional force exerted by the rope on the climber?
- A cube slides down the surface of a ramp at a constant velocity. What is the magnitude of the frictional force that acts on the cube due to the surface?

- Two different experiments, P and Q, generate two sets of data to confirm the proportionality of variables x and y. The graphs for the data from P and Q are shown. The maximum and minimum gradient lines are shown for both sets of data. What is true about the systematic error and the uncertainty of the gradient when P is compared to Q?
- The road from city X to city Y is 1000 km long. The displacement is 800 km from X to Y.
- What is the distance travelled from Y to X and the displacement from Y to X?
- A car accelerates uniformly from rest to a velocity v during time t_1. It then continues at constant velocity v from t_1 to time t_2.
What is the total distance covered by the car in t_2?
- An object is sliding from rest down a frictionless inclined plane. The object slides 1.0 m during the first second. What distance will the object slide during the next second?
- A rocket has just been launched vertically from Earth. The image shows the free-body diagram of the rocket. F1 represents a larger force than F2.
- Which force pairs with F1 and which force pairs with F2, according to Newton’s third law?
-
Two blocks of different masses are released from identical springs of elastic constant k = 100 Nm−1, initially compressed a distance Δx = 0.1 m. Block X has a mass of 1 kg and block Y has a mass of 0.25 kg.

What are the velocities of the blocks when they leave the springs?
