A helicopter drops a box from 120m in the air.
a. Determine the time the box is in the air.
b. determine the velocity the box would have right before it hits the ground
c. Before the helicopter had a horizontal velocity of 55/s. Determine the distance the box will travel in the x-axis.
d. solve for the Resultant velocity that the box would impact the ground with.
I know it's a long question, but I'm really lost! Thank you! :)
