Unformatted text preview: www.clas.ucsb.edu/staff/vince Physics 6A Ch 4 In Class Worksheet (Page 2) 3) Jack and Jill lift upward on a 1.3kg pail of water, with Jack exerting a force F 1 of magnitude 7.0N and Jill exerting a force F 2 of magnitude 11.0N. Jills force is exerted at an angle of 28 degrees with the vertical, as shown below. At what angle with respect to the vertical should Jack exert his force if the pail is to accelerate straight upward? Find the acceleration. 4) A 6.0kg block of ice is acted on by two forces, F 1 and F 2 , as shown in the diagram. If the magnitudes of the forces are F 1 =13N and F 2 = 11N, find (a) the acceleration of the ice and (b) the normal force exerted on it by the table....
