3. As a boat crests the top of a hill and starts down the other side, it is moving at 2.3 m/s. It takes 3.2 seconds to get to the bottom of the 38 m ramp.
a. Calculate the speed of the boat just before it hits the pool at the bottom of the ramp.
HINT: Calculate acceleration 1st.
b. The passengers in the boat get soaked in the pool at the bottom – and then realize that the boat is moving much slower than it was before it “dove” into the pool. They observe that it takes their boat, which is 2.85 m long, 1.95 sec to pass a stationary post along the side of the flume. What is the speed of the boat after it leaves the pool?
c. If the “splash down” (change in velocity from the speed in “a” to the speed in “b”) took 3.43 seconds, what was the acceleration of the boat during splash down?
d. Calculate how far the boat moved while it was slowing down.
