1. A cannon fires a cannonball from the top of a wall at a speed of 113.26 m/s and an angle of 28.78 degrees from the horizontal. A cannonball that was accidentally dropped from the top of the castle hits the water below in 2.35 s. What is the horizontal distance from the wall where the fired cannonball hits the ground?

2. A car is traveling at 58.21 mph. The driver applies the brakes and the car decelerates at 4.53 m/s². What is the stopping distance in meters?

A cannon on a train car fires a projectile to the right with speed v0, relative to the train, from a barrel elevated at angle θ. The cannon fires just as the train, which had been cruising to the right along a level track with speed vtrain, begins to accelerate with acceleration a, which can be either positive (speeding up) or negative (slowing down). Find an expression for the angle at which the projectile should be fired so that it...
