Physics 11 - Unit 3 Review
1. A monkey on a raft is crossing a river that flows to the east at 8.0 m/s. His top paddling speed is 12.0 m/s.
He points due south and attempts to cross. If the river is 120 m wide, how far downstream will he end up
when he reaches the other side?
2. Starscream can fly at a speed of 885 km/h. If he flies north while a wind blows at 125 km/h to the west, find
his resultant velocity
3. Knightboat is attempting to cross a river that flows from north to south at 18 m/s. His top speed is 31 m/s.
At what heading should he cross the river if he starts on the East bank and needs to end up directly across on
the other side?
4. A ball rolls off of a 1,5 m high table at 6.5 m/s. How far away from the table does it hit the floor?
5. A pumpkin cannon-retrofitted to launch hamsters - is aimed at 38° above the horizontal and fired across a
flat field at a velocity of 85 m/s. How far does the hamster fly?
6. Mr. Miagi drop kicks the Karate Kid and he flies off at 28 m/s 55° above the horizontal. How long does it
take him to reach the top of his are?
7) A football is booted with an initial velocity of 18 m/s 55° above the horizontal. What is its speed at the top
of its arc?
