ASAP PLEASE An object accelerates from a stop at 5m/s^2 to the east. After 10 seconds it reaches its maximum velocity. After another 75 seconds it turns back toward the starting point. It immediately slows down and moves at 15m/s until it reaches the start point where it stops.

A. What is the avg velocity of the object

B. How Far East does the object travel?

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
