A 5.000kg mass starts from rest and slides down on an inclined plane, hits a bumper at the bottom of the inclined plane and bounces back up the inclined plane and comes to rest again. Through the collision with the bumper, 0.700J of energy is lost. The mass started at a height of 0.250m above the bumper and rebounded to a height of 0.210m after the collision. How much energy was lost in from when the mass started at rest until it rebounded to its maximum height after the collision?
You inflate the front tires on your car to 29 psi. Later, you measure your blood pressure, obtaining a reading of 138/84, the readings being in mm Hg. In metric countries (which is to say, most of the world), these pressures are customarily reported ..
