The vehicle land-speed record has long been held by rocket cars. These vehicles resemble the high-speed rocket planes that were used in the early days of the space program, but they have heavy metal wheels. On September 5, 1997, the world land-speed record was set by the British-built Thrust SSC rocket car, which had a top recorded speed of 341 m/s. The kinetic energy of the car at this speed is 5.289 108 J. What is the cars mass?

A mass of M-kg rests on a frictionless ramp inclined at 30. A string with a linear mass density of =0.025" kg/m" is attached to the M-kg mass. The string passes over a frictionless pulley of negligible mass and is attached to a hanging mass (m). The system is in static equilibrium. A wave is induced on the string and travels up the ramp. (a) Show that the mass of M is equal to twice the mass of the hanging mass: M = 2m.(b) and at what wave speed does the wave travel up the string, if m = 5 kg?
