1. a) Write down the four equations of motion, explaining any symbols that you use and the units for each quantity. b) Complete the table: Final velocity (m/s) | Initial velocity (m/s) Acceleration (m/s-) Time (s) Distance (m) A 60 20 4 B 0 10 C 30 -2 12 0 10 150 2. A pupil observes the motion of an object and produces the following graph Velocity ms" a) i) How do you find acceleration from a velocity-time graph? ii) Use this method to find the accelerations for AB, BC, CD b) i) How do you find distance travelled from a velocity-time 10 graph? ii Find the distance travelled between A and C using this 6 12 14 Time /s method 3. a) Describe the motion in each of these velocity-time graphs. b) i) What does the gradient of a displacement-time graph tell you? ii) Describe the motion in each of these displacement-time graphs. displacement displacement displacement c) draw the velocity-time graph which corresponds to this Displacement displacement-time graph. m 170 80 t /seconds 4. a) A child threw his teddy bear from an upstairs window. If it hit the ground 1.5s later what was its velocity just before impact? (g=10m/s-) b) What distance did it fall? 5. Some aliens landed on an unexplored planet and wanted to find the acceleration due to gravity of the planet. So one of them jumped off a cliff 300m high and landed at the bottom 10 seconds later. What did they find the acceleration to be
