QUESTION A 1348.0 g mass is on a horizontal surface with μk = 0.44, and is in contact with a massless spring with a force constant of 559.0 N/m which is compressed. When the spring is released, it does 6.29 J of work on the mass while returning to its equilibrium position. Calculate the distance […]
QUESTION The drawing below shows a hydraulic chamber in which a spring (spring constant = 1650 N/m) is attached to the input piston (A1 = 16.3 cm2), and a rock of mass 40.7 kg rests on the output plunger (A2 = 65.1 cm2). The piston and plunger are nearly at the same height, and each […]
QUESTION A 475 kg satellite is in a circular orbit at an altitude of 525 km above the Earth’s surface. Because of air friction, the satellite eventually falls to the Earth’s surface, where it hits the ground with a speed of 2.30 km/s. How much energy was transformed into internal energy by means of air […]
QUESTION A satellite of mass m is in a circular orbit of radius R2 around a spherical planet of radius R1 made of a material with density p . ( R2 is measured from the center of the planet, not its surface.) Use G for the universal gravitational constant.Find the kinetic energy of this satellite,K […]
