QUESTION 4 QUESTION 4 A Mercedes SmаrtCаr with а mass оf 880 kg stands still at a traffic light. The оccupant weighs 55kg. It is hit frоm behind by a minibus with a mass of 2 800 kg, which moves at a velocity of 20 m.s-1. Immediately after the collision, the car moves forward at 12 m.s-1. 4.1 Write the law of conservation of linear momentum in words. (2) 4.2 Calculate the speed of the minibus directly after the collision. Use right as positive. (4) 4.3 The driver of the minibus does NOT wear his seat belt. Describe the movement of the driver directly after the collision. (2) 4.4 State the law of physics that explains the driver's motion in Question 4.3 in words. (2) Robyn rides a horse on her grandfather's farm at a constant speed of 6.5m.s-1 when the horse bucks and Robyn flies over the top of the horse's head at a speed of 3.8m.s-1. The horse keeps running forward at a speed of 8.5 m.s-1. The mass of the horse is 65kg. 4.5 Does Robyn and the horse serve as one or two separate objects, before she is thrown. Explain your answer. (2) 4.6 Determine Robyn’s mass. (4) Most sports shoes have a built-in system that helps absorb the force of the impact when athletes' heels hit the ground. The graph below is a representation of the maximum impact force for three different brands of sports shoes, used on the same type of surface, over a period of time. 4.7 Define impulse. (2) 4.8 Which one of the three brands of sports shoes, A, B or C should NOT be recommended to athletes so that their injuries can be minimal? (1) 4.9 Explain the answer in Question 4.8. (3) [22] Please do not submit any answers in the block below.
