The bodysuits are made of soft plastic and are inflated with air. The inflatable bodysuits allow the two people to collide with each other safely. Figure 1 Inflatable bodysuit Person The two people run towards each other before colliding and coming to a stop. IMI G/Jun24/8465/3F {o[3}.[4] {o[3}-[2] 11 11 11 | Do not write People wearing bodysuits take more time to stop during a collision than people not wearing bodysuits. How does wearing bodysuits affect the deceleration of the people during the collision? [1 mark] Tick (Vv) one box. The deceleration is less. The deceleration is the same. The deceleration is greater. How does wearing bodysuits affect the impact force experienced by each person during the collision? [1 mark] Tick (“) one box. The impact force is less. The impact force is the same. The impact force is greater. Question 3 continues on the next page Turn over > G/Jun24/8465/3F outside the box 13 13 Do not write outside the box [0 [3]-[4] After the collision, person B has 45 J of kinetic energy. Person B has a mass of 40 kg. Calculate the speed of person B after the collision. Use the equation: 2 x kinetic energy speed = |———_____— . mass [2 marks] Speed = m/s Question 3 continues on the next page Turn over > 13 G/Jun24/8465/3F 14 14 Catal the outside the Figure 3 shows a person in an inflatable sphere rolling down a hill. box Figure 3 Person in inflatable sphere -[5] Describe how the gravitational potential energy and kinetic energy of the person vary as the sphere rolls down the hill. [2 marks] [0 [3]-[6] Suggest two factors that affect the maximum speed of the person as the sphere reaches the bottom of the hill.
