Suppose that a car oscillates vertically as if it were a mass m = 800 kg on a single spring with constant 7 x 104 N/m, attached to a single dashpot with constant 3000 N·s/m. Suppose that this car with the dashpot disconnected is driven along a washboard road surface with an amplitude of 5 cm and a wavelength of L = 10 m. At what car speed will resonance vibrations occur? In the example, assume that the car is moving with the constant speed of 25 m/s on the washboard under the same conditions as described. Find the equation of oscillations of the car and solve it. Your solution must have two arbitrary constants C1,C2.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage
