An artificial earth satellite has a circular orbit of radius 7.33 * 10 ^ 6 m (which means it is orbiting approximately 970 km above the surface of the earth) in an equatorial plane. The period t(the time for one complete orbit) is 5.69*10^3s(about 1.58 h). Compute the constant speed of the satellite? And if the satellite is directly above the equator and traveling east at time t, find the average acceleration during the time interval from t to t +T/40.0? And find the satellite instantaneous acceleration at the time t?

A ball is thrown eastward into the air from the origin (in the direction of the positive x-axis). The initial velocity is 40 i +64 k, with speed measured in feet per second. The spin of the ball results in a southward acceleration of 4 ft/s2, so the acceleration vector is a = -4 j - 32 k. Where does the ball land? (Round your answers to one decimal place.) X ft from the origin at an angle of 5.7 X from the eastern direction toward the south. 80.4 With what speed does the ball hit the ground?

How would I begin to solve this problem? In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for a rocket's position measured from the center of the Earth is given by y(t) = (RE3/2 + 3*(g/2)1/2 REt)2/3 where RE is the radius of the Earth (6.38 ✕ 106 m) and g is the constant acceleration of an object in free fall near the Earth's surface (9.81 m/s2). (a) Derive expressions for vy(t) and ay(t). (Use the following as necessary: g, RE, and t. Do not substitute numerical values; use variables only.)
