Don't forget .... there could be a quiz next class. Ooohhhhhhh.............
1. Finish the Moon/Earth problem from last class.
2. A ball kicked upwards (at the edge of a cliff) with an initial speed of 35 m/s. It goes up, achieves apogee, and comes down along the side of the cliff, landing 20 m below where it was launched. Find the total time in air. I suggest the approach wherein you use the quadratic formula, but any good approach is fine by me.
3. Consider dropping a pebble into a river below you (standing on a bridge). The splash occurs 2.4 seconds after you drop it. How high up is your bridge?
4. A car accelerates at 2 m/s^2 for 5 seconds. Then it maintains its velocity for 10 seconds. Then the driver applies the brakes for 2 seconds to bring the car to a halt.
a. how far did the car travel during the entire trip? (Break it into little chunks of the trip.)
b. draw the 3 related graphs of motion for this trip.
