Q1. A hotel elevator ascends 270 m with a maximum speed of 5.0 m/s. Its acceleration and deceleration both have a magnitude of 1.7 m/s2.

Q2. An artillery shell is fired with the initial velocity of 300 m/s at 54.7° above the horizontal. To clear an avalanche, it explodes on the mountainside 55.0 s after firing. What is the x and y components of the shell where it explodes, relative to its firing point?
