(a) As the lander is descending, if the pilot decides to shut down the engine when the lander is at a height of 2.2 m, (this may not be a safe height to shut down the engine) and the velocity of the lander (relative to the surface of the planet) is 1.6 m/s what will be velocity of the lander at impact

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5
