As a SOO-kg Moon lander is descending toward the surface, its thruster res an upward force. At a height of 50 m, the lander's velocity is 9.5 m/s downward. At a height of 5 m, its velocity is 0.5 m/s downward. The Moon's gravitational eld strength near its surface is 1.6 N/kg. Assume the mass of the lander remains nearly constant during the process. Part 1 What is the average y-velocity of the lander during this displacement? Uavg,y = n m/s Save to r Late r Attempts: O of 4 used Part 2 What is the time interval during which this displacement occurs? Ar=l 5 Save fo r Late r Attempts: 0 of 4 used Part 3 What is the y-component of the average net force on the lander during this time interval? Fnet,y = n N eTextbook and Media Assistance Used
