A fighter jet is launched from an aircraft carrier with the aid of its own engines and a steam-powered catapult. The thrust of its engines is 1.12×105 N. In being launched from rest it moves through a distance of 54.0 m and has a kinetic energy of 6.01×107 J at lift-off. What is the work done on the jet by the catapult? Number Units

The figure shows a cold package of hot dogs sliding rightward across a frictionless floor through a distance d = 21.0 cm while three forces act on the package. Two of them are horizontal and have the magnitudes F1 = 9.0 N and F2 = 2.0 N; the third is angled down by Θ = 60.0∘ and has the magnitude F3 = 7.0 N. (a) For the 21.0 cm displacement, what is the net work done on the package by the three applied forces, the gravitational force on the package, and the normal force on the package? (b) If the package has a mass of 3.0 kg and an initial kinetic energy of 0, what is its speed (in m/s) at the end of the displacement? (a) Number Units (b) Number Units

A pendulum, comprised of a light string of length L and a small sphere (its radius is much smaller than L or d ), swings in the vertical plane. The pendulum is released from rest at the horizontal position (θ = 90∘). During the swing, the string bends around a peg located a distance d below the point of suspension, and the pendulum swings a full circle around the peg. We choose d to be the smallest distance that allows this to happen. a) At this value of d, what is the kinetic energy of the pendulum at the top of the circular swing? b) What is d in terms of L ? c) Discuss how the results for (a) and (b) would change if the pendulum moves against air resistance throughout its path. No calculations are required but you should answer in terms of work and energy.
