Q1. Torgue 10 Points 3 Forces are applied to the lever system as shown in fig 1.: fig 1. 2000MN 2 1200M What class of lever is this system? (1pt) What direction will the system rotate? (1pt) What is the total magnitude of torgue on this system? (5pts) Explain how a force may provide a negative torque while pushing a system in a positive direction. (3pts) Q2. Friction 10 points A 4dkg sled is already in motion along a horizontal ice surface with a puk = 0.06 Two children sit on the sled, one with a mass of 21kg and the other with a mass of 14kg. The sled is pulled forward at 25 above parallel with a force of 1100N. d. b. What is the normal reaction force of this sled system? (2pts) What is the acceleration of the sled with both children on it? (5pts) Which of Newton's laws informs the concept of Normal Reaction force? (1pt.) How do the perpendicular forces between two objects in contact create resistance to parallel (sliding) movement between those objecis? (2pts) pk=0.06
