These are the problems we will do at the review session.

If you are planning on coming to the review sessison you can print these out if you like but I would not attempt them until you get to the review session.

If you can't make the review session feel free to work on these, but I would encourage you do them like you are taking an exam and then check the answers at the bottom of the page.

 

#1. A motorcyclist moving with an initial velocity of 8.0 m/s undergoes a constant acceleration for 3.0 s, at which time her velocity is 17.0 m/s.
a. Sketch a x vs. t graph.
b. Sketch a v vs. t graph.
c. What is her acceleration?
d. How far does she travel during that 3.0-s interval?

#2. A ball is thrown upward from the ground with an initial speed of 25 m/s; at the same instant, another ball is dropped from a building 15 m high.
a. Sketch a y vs. t graph.
b. Sketch a v vs. t graph.
c. Find the height at which the balls meet.

#3. Vector A has a magnitude of 6.00 m and points 30.0o north of east. Vector B has a magnitude of 4.00 m and points 40.0o south of west. What is the resultant of adding these two vectors together?

#4. Noobus is a death-defying squirrel with miraculous jumping abilities. Running to the edge of a flat rooftop, she leaps horizontally with a speed of 6.00 m/s. If she just clears the 3.00 m gap between the houses and lands on the neighbor's roof, what is her speed upon landing? Sketch a y vs. x graph.

#5. A projectile is shot from the edge of a vertical cliff 60.0 m above the ocean. It has a speed of 101 m/s and is fired at an angle of 35.0o above the horizontal.
a. Sketch a y vs. x graph.
b. How far from the foot of the vertical cliff does the projectile hit the water?

#6. A passenger walks from one side of a ferry to the other side as it approaches a dock. If the passenger's velocity is 1.50 m/s due north relative to the ferry, and 4.50 m/s west relative to the water, waht are the direction and magnitude of the ferry's velocity relative to the water?
