1. a man stands on top of a 25 m tall cliff. the man throws a rock upwards at a 25-degree angle above the horizontal with an initial velocity of 7.2 m/s. what will be the vertical position of the rock at t = 2 seconds? what will be the horizontal position of the rock at that time?
2. a cannon fires a cannonball forward at a velocity of 48.1 m/s horizontally. if the cannon is on a mounted wagon 1.5 m tall, how far would the cannonball travel before it lands on the ground?
3. look at the following picture. what would be the resultant vector of a+b?
4. an airplane undergoes the following displacements: first, it flies 72 km in a direction 30° east of north. next, it flies 48 km due south. finally, it flies 100 km 30° north of west. using analytical methods, determine how far the airplane ends up from its starting point.
5.the following picture shows a golf ball being hit and given an initial velocity of v0. the ball is hit at an unknown angle above the ground. what are two values that are known, even in the absence of all other numbers?
