Question

1. Work in 2-D. A particle is given a displacement Δr = (2.0m)i – (5.0m)j along a straight line. During the displacement, a constant force F = (3.0N)i + (4.0N)j acts on the particle. (a)Find the work done by the force, and (b) the component of the force in the direction of the displacement. 2. Work-Kinetic Energy Theorem. A truck of mass 3000 kg is to be loaded onto a ship by a crane that exerts an upward force of 31.0 kN (kilo Newtons) on the truck. This force, which is just strong enough to get the truck started upward, is applied over 2.00 m. Find (a) the work done by the crane, (b) the work done by gravity, and (c) the upward speed of the truck after 2.00 m. 3. Law of Conservation of Energy. Two snow-covered peaks are at elevations of 862 m and 741 m above the valley between them. If a skier starts from rest on the higher peak and just coasted down without exerting any effort, at what speed would he arrive at the lower peak? 4. Power and Kinetic Energy (PΔt = ΔK). A new sports car can accelerate from 0 to 96 kph in 6.5 s. How quickly would you expect it to be able to accelerate from 80 kph to 112 kph?
