A cannonball is shot (from ground level) with an initial horizontal velocity of 40 m/s and an initial vertical velocity of 29 m/s.
1) What is the initial speed of the cannonball?
2) What is the initial angle ? of the cannonball with respect to the ground?
3) What is the maximum height the cannonball goes above the ground?
4) How far from where it was shot will the cannonball land?
5) What is the speed of the cannonball 1.5 seconds after it was shot?
6) How high above the ground is the cannonball 1.5 seconds after it is shot?

Two boats start together and race across a 46 km wide lake and back. Boat A goes across at 44 km/h and returns at 48 km/h. Boat B goes across at 27 km/h, and its crew, realizing how far behind it is getting, returns at 69 km/h. Turnaround times are n..
A cowboy at a dude ranch fills a horse trough that is 1.5 m long, 60 cm wide and 40 cm deep. He uses a 2.0cmdiameter hose from which water emerges at 1.5m/s. How long does it take him to fill the trough.
