+178 An object is located 10km at t=0 above a planet's surface with speed = 0, given the following statements:
1.The planet's atmosphere is identical everywhere along the 10km depth.
2.The object's atmospheric decceleration is -1.5m/s^2 per 70m/s.
3.The gravity is constant throughout the 10km depth. (i.e. No considerations for gravity decreasing over distance to the core and relativistic effects.)
4.The planet's gravitational acceleration = 8m/s^2.
5.The object weights 30 kg.
Given the statements above, consider and answer the following questions: (Show your process in full details.)
1.The terminal velocity of the atmosphere?
2.The momentum the object have when it hits the ground? (Express your answer in Joules.)
3.The net acceleration at t=10 sec?
