PHYSICS F3 HOLIDAY ASSIGNMENT APR 2024 1. Distinguish between distance and displacement, giving its SI units? (2mks) 2. A car is brought to rest from a 90km/h in 26 s. determine its acceleration. (3mks) 3. The table below shows the position of displacement at different points in time for a particle in motion Time(s) 0 s) 0 10 20 30 40 50 600 700 320 200 S (m) 0 10 20 40 65 100 150 (a) Plot a graph of displacement (s) against time for the motion (5mks) (b) From the graph, determine the velocities at times t=24 s and 74 s. hence, determine the average acceleration over this time interval. (3mks) 4. A stone is projected vertically upwards with a velocity of 30 m/s from the ground. Calculate; (a) The time it takes to reach the maximum height (2mks) (b) The time of flight (2mks) (c) The maximum height reached (2mks) (d) The velocity with which it lands on the ground. (Take g=9.8m/s) (2mks) 5. What is refraction of light? 6. State 2 laws of refraction of light. 7. Given that refractive index of diamond is 2.42 and velocity of light in air is 3.0 x 10% m/s, calculate the velocity of light in diamond. (3mks) 8. In an experiment to determine the refractive index of a material using real and apparent depth method, the following results were obtained Real 5 10 15 20 25 30​
