Kinetic energy is ancther engineering quantity that is mass dependent. An object having a mass m and moving with a speed V has a kinetic energy equal to ?m!,j. Compute the kinetic energy for the following situations. (a) a 2,000 kg car moving at a spead of 140 km/h What is a speed of 140 km/h in m/s? o me Compute the kinetic energy for the car (in J). b Caonvert the kinetic energy for the car to U.S. Customary units (ft - Ibf). (b) a 280,000 kg Boeing 777 moving at a speed of 710 km/h What is a speed of 710 km/h in m/s? L Compute the kinetic energy for the plane (in 3). . h Convert the kinetic energy for the plane to U.S. Customary units (ft - 1bf)
