Assume that the kinetic energy of a 1350 kg car moving at 135 km/hr could be converted entirely into heat. What amount of water could be heated from 23 (degrees C) to 45 (degrees C) by the car's energy?
Q) What is the kinetic energy, in joules, of a molecule of oxygen moving at a speed of 255 m/s(use the appropriate prefix to avoid exponential notation) a) The equation for kinetic energy is ½mv2, and is in units of joules. What are the component units for joules in terms of mass and velocity? kg m^2/s^2 b) From the previous part, we know that the mass needs to be in units of kg. What is the mass of an oxygen...
A truck with failed brakes is moving downgrade at 120 km/hr just before the driver steers the truck up an emergency escape ramp with an inclination of theta= 15 degrees. The trucks mass is 1.4x10^4 kg. Assume that the rolling friction behaves like kinetic friction, and the coefficient of rolling friction between the tires and ramp is 0.10. What minimum length L must the ramp have if the truck is to stop (momentarily) along it?
