Q1. An artillery shell is fired with an initial velocity of 303 m/s at 46° above the horizontal. To clear an avalanche, it explodes on the mountainside 47.5 s after firing. What is the x and y components of the shell where it explodes, comparative to its firing point?
Q2. A kayaker needs to paddle north across an 85 m wide harbor. The tide is going out, creating a tidal current that flows to the east at 1.7 m/s. The kayaker can paddle with the speed of 3.0 m/s.
