2 A student slid а smаll metаl cube dоwn a frictiоnless ramp. The cube cоllided with a fixed metal block at the bottom of the ramp. The student released the cube from position X as shown in the diagram. After the collision, the cube rebounded to position Y. See addendum Figure 2.1 The student measured heights h and r. He then repeated the experiment using several different starting positions. (a) The student recorded his results in the table below. See addendum Figure 2.2 (i) Criticise these results. (2) (ii) Plot a graph of r on the y-axis and h on the x-axis. (5) (b) (i) Show that the velocity u of the cube immediately before the collision is given by (2) (ii) The coefficient of restitution (denoted by e) is the ratio of the final to initial relative speed between two objects after they collide. It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision. The coefficient of restitution e is given by the equation where v is the velocity of the cube immediately after the collision. Explain why the gradient of the graph is e2. (3) (c) The student researched the range of values for the coefficients of restitution e of different metals. stainless steel 0.63 < e < 0.93 cast iron 0.3 < e < 0.6 Determine which of these metals the cube could be made from. (3) (d) Explain how friction between the cube and the surface of the ramp would affect the value obtained for e. (2) (Total for question 2 = 17 marks)
3 A student determined the viscоsity оf а liquid. The student meаsured the fоrce required to pull а small sphere upwards through the liquid at a constant speed. See addendum Figure 3.1 (a) The student measured the diameter of the sphere using a micrometer. See addendum Figure 3.2 Calculate the percentage uncertainty in the diameter of the sphere shown on the micrometer. (3) (b) State one precaution that should be taken before using a micrometer. (1) (c) The student measured the value of force when the sphere was suspended and stationary in the liquid. The force meter used is shown in the photograph. See addendum Figure 3.3 When the sphere was stationary the reading on the force meter was 0.20 N. The student then moved the force meter upwards so that the sphere moved at a constant speed of 0.32 m s−1. The reading on the force meter was 0.29 N (i) Explain why it was necessary to measure the force when the sphere was stationary and the force when the sphere was moving at constant speed. (3) (ii) Calculate the viscosity η of the liquid. (3) (d) The resolution of the force meter was 0.01 N. The distance moved between the rubber bands was 25.0 cm. The time measured was 0.78 s. The percentage uncertainty in the measurement of the diameter was negligible. Assess which of these measurements was the most significant source of uncertainty in the value of viscosity.
