1. When visiting Yosemite, campers staying in Curry Village are warned by park rangers to store food in lockers outside the cabins to keep bears from getting into your supplies (and never leave food in your car bears have broken in to get at a single candy bar wrapper). However, bear lockers are not available when camping in the wilderness and the next best alternative is to hang up your pack. Consider a 26 kilogram pack seen the two circumstances in the figures below. (a) In the first case, the ropes were of different lengths and the pack hangs at the angles seen. Calculate the tension in the two ropes. (b) The first situation hung too low, making the pack accessible to the bear. So, you've shortened the longer rope to hang the pack as seen in the second case. Now what is the tension in the ropes? Vn² 2. A block slides down a frictionless plane having an inclination angle of 0= 15°. The block starts from rest at the top, and the length of the incline is 2.00 m. (a) Draw a freebody diagram for the block. (b) Find the acceleration of the block, and (e) find the speed of the block when it reaches the bottom of the incline. 3. A time-dependent force F = (8.00 -4.006) N is exerted on a 2.00 kg object initially at rest. (a) At what time will the object be moving with a speed of 15.0 m/s? (b) How far is object from its initial position when its speed is 15.0 m/s? (c) Through what total displacement has the object traveled at this moment? 1.
