As a body is projected to a high altitude above the earths surface, the variation of the acceleration of gravity with respect to altitude y must be taken into account. Neglecting air resistance, this acceleration is determined from the formula a=−g0[R2/(R+y)2], where g0 = 9.81 m/s2 is the constant gravitational acceleration at sea level, R = 6356 km is the radius of the earth, and the positive direction is measured upward.

With what velocity does the particle strike the earth if it is released from rest at an altitude y0 = 750 km?

A satellite is launched into an orbit at an altitude 200 km above the surface. Onboard is an exquisitely sensitive atomic clock that is synchronized with an identical clock on Earth. After orbiting for one year, the satellite is captured, returned to Earth, and the clocks compared. What will be the shift in time between the two clocks?

1. Mary is aware of the many ways the body adapts to training at high altitude. She is a competitive runner and wonders if training in high-altitude environments will help her performance at sea level. She wants to implement a "live high, train low" strategy. How could she achieve this? a. Live and train at high altitude for one month and then compete at sea level. b. Move to a town with higher elevation and train in her neighborhood. c....

For the earth, a reasonable estimate of the variation of pressure with altitude can be made for a gas of molecular weight, M, assuming the atmosphere is isothermal, the variation of g with altitude is negligible, and that the atmosphere behaves like an ideal gas. (a) Under these assumptions how does the pressure vary with altitude in terms of the altitude, y, molecular weight of the gas, M, gas temperature, T, and appropriate constants? (b) How does the number density...

A 425 kg satellite is in a circular orbit at an altitude of 400 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 2.00 km/s. How much energy was transformed to internal energy by means of friction? J
