Question 1. Find out how fast a GPS satellite is moving relative to someone on the ground and from that how much slower time runs where it is in orbit relative to someone on the ground.Question 2. Calculate the overall ratio of clock time on a satellite to clock time on the earth. In particular, if you’re on earth and 1 second passes on an earth clock, how much time passes on a satellite clock? Explain it.
What is the kinetic energy of an ideal projectile of mass 15.3 kg at an apex (highest point) of its trajectory, if it was launched with an initial speed of 42.5 m/s and an initial angle of 41.5° respecting the horizontal.
What is the change in kinetic energy of the puck
Megan's mass is 27 kg. She climbs the 4.8 m ladder of a slide and reaches a velocity of 3.6 m/s at the bottom of the slide. How much work was completed by friction on Megan? Imagine that air resistance is negligible.
What is used up electric potential energy of charge carriers
A weather vane at first at rest has a moment of inertia of 0.111 kg • m2 about its axis of rotation. A 53.0 g piece of clay is thrown at the vane and sticks to it at a point 19.5 cm from the axis. The initial velocity of the clay is 20.0 m/s, directe..
