The parachute on a racecar, which weighs 8820 N, opens at the end of the quarter-run to stop the car motion, while it is moving at 33 m/s. Assume upward and rightward are positive. Round all answers to 3 decimal places.

A cannonball is launched from the top of a flat mountainside, which slopes upwards at35 degrees with respect to the horizontal. The cannonball exits the cannon moving at150 m/s, at an angle of 55 degrees with respect to the horizontal.a) How much time (in seconds) elapses between the moment the cannonball isfired and the moment it lands on the mountainside.b) How far down the mountainside (in meters) does the cannonball land?

A river 109.5 m wide flows toward the south at 35.0 m/min. A girl on the west bank wishes to reach the east bank in the least possible time. She can swim 109.5 m in still water in 1.10min. How long does it take her to cross the river? Also how far downstream does she travel? What is her velocity relative to land?find the magnitude and direction south of east? Also what is the total distance she traveled? And last in what direction must she swim if she wishes to travel straight across the river?

An airplane starts at rest and accelerates at 8.4 m/s^2at an angle of 35 degrees south of west. After 11 s, how far in the westernly direction has the plane traveled? After 11 s how far has the plane traveled in the southernly direction?
