You can choose to show your work and use significant digits as you learned in grade 11. But make sure to state your variables and the start and write a sentence with the answer at the end. Use 9.8N/kg[down] for g. Vector quantities must be written with a direction. QUESTION 1 A ride in the amusement park goes up and down. The ride launches a rider of mass 62kg from an initial velocity of 0.0m/s[up], to a final velocity of 9.3m/s [up] and that takes a time of 0.36 seconds. Calculate the normal force that the guest experiences from the seat during that time, in which the guest experiences only two forces: normal force and gravity. QUESTION 2 A fisher pulls a sled of fish and they are travelling at a constant velocity of 1.2 m/s [forward]. The sled and the fish have a combined mass of 11kg. These sled and the fish can be treated as one object for the problem. There are four forces acting on the sled of fish: The fisher pulls with a force of 41 N [39 degrees forward above the horizontal]. a) Calculate the magnitude of the force of gravity downwards. b) Calculate the magnitude of the force of kinetic friction backwards. c) Calculate the magnitude of the normal force from the ground upwards. d) Calculate the coefficient of kinetic friction between the sled and the ground?
