A science student is riding on a flatcar of a train traveling along a straight, horizontal track at a constant speed of 10.0 m/s. The student throws a ball into the air along a path that he judges to make an initial angle of 60.0° with the horizontal and to be in line with the track. The student’s professor, who is standing on the ground nearby, observes the ball to rise vertically. How high does she see the ball rise?

In the middle of the night you are standing a horizontal distance of
14.0 m from the high fence that surrounds the estate of your rich
uncle. The top of the fence is 5.00 m above the ground. You have taped
an important message to a rock that you want to throw over the fence.
The ground is level, and the width of the fence is small enough to be
ignored. You throw the rock from a height of 1.60 m above the ground
and at an angle of 48.0° above the horizontal.
Part A

- Question: Diego is getting hungry and acting like a typical saber-toothed tiger. He visualizes Sid as a hunk of meat and begins to chase him frantically around the ground. First, Sid darts 50.0 meters at 35.0° NoW and then turns abruptly and races 40.0 m S. If Manny ran from where they were originally standing to where Sid ended up, how far and in what direction would Manny have to run to break up the fight? Use the triangle method to solve this. Should you use the component method, I will award zero points. I know the answer I just don’t know how to get it.

- Dennis, a senior in high school, is preparing for the greatest food fight prank of all time. He plans to launch watermelons from his homemade melon cannon machine towards the enemy food fighters standing on the rooftop lunch area. The enemies are 10 meters from the edge of the 7-meter-high balcony. Dennis plans to hide in some bushes away from the building to fire his cannon. The cannon fires at 22.0 m/s & must be angled 40° above ground to clear the bushes. a. How far from the base of the building should Dennis place the cannon? b. The teachers' lounge window is 14 above the ground.

A person standing in the flatbed of the pickup truck throws a ball into the air at an angle of 60° above the horizontal as measured relative to the truck and in line with the highway. A second person who is standing on the ground nearby observes the ball to rise vertically.
