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?
