Paper 1 H - SAMPLE SET 1 Q24
24) A free-fall skydiver falls from a plane and reaches terminal velocity after 15 seconds.
Look at the graph of her motion.
Look at the graph of her motion.
(a) Use the graph to find the acceleration at 5 seconds. [3]
answer: ........................... m/s2
(b) Use the graph to find the distance travelled between 0 and 2.5 seconds.
answer: ........................... m
(c) A skydiver jumps from an aeroplane, falls towards the ground, opens her parachute and falls
safely to earth.
Look at the graph of the velocity of the skydiver as she falls.
Look at these regions of the graph:
> x
> y
Use ideas about forces to explain the motion during x and y. [6]
