1.5 In this figure, force F is pulling the rope (wrapped around the drum). There is no slippage between the ground and the larger radius drum. Pick one: rolls A The drum rotates in the counter-clockwise direction (B The visible portion is getting longer (unwinding)< -wrapping (C) The direction of friction from the ground on the drum is to the left (D) The direction of friction from the ground on the drum is to the right 1.6 Rob AB is released from horizontal position and hits CD when it gets to the 6 o'clock position. During the collision (pick one) (A) No impulsive forces if e = 1 (B))Impulsive forces between ends A and C only TT) Impulsive forces at support point B only (D) Impulsive forces betwwen A and C and at support B In the figure below, u (coeff. of friction) between the ground and wheels of the cart is 1.7 the same as the u between the cart and cylinder. Cylinder is then is pulled by the force P as shown. Pick one: (A) Cart will not move (B) Jart and cylinder will move together B teT If P is large engouh, both will move together (D) There can be no slippage between the cart and the cylinder
