1.) A ball is thrown horizontally from a height of 1 m and lands 5 m away. a. What is the time of flight of the ball?

b. What is the initial velocity of the ball?

2.) A potato gun is fired horizontally from a height of 1.5 meters with the potato launched at 25 m/s.

a. What is the time of flight of the potato?

b. How far from the gun will the potato land?

3.) A water park is designing a new water slide that finishes with the rider flying horizontally off the bottom of the slide. The slide is designed to end 1.2 m above the water level, and the average rider is estimated to leave the bottom of the slide at 25 m/s. How far will the rider fly through the air before hitting the water?

4.) A marble rolls horizontally off a table that is 0.8 m tall. If the marble lands 0.6 m from the base of the table, what is the initial velocity of the marble?

5.) The launch velocity of a toy car launcher is determined to be 5 m/s. If the car is to be launched from a height of 0.5 m, where should a target be placed so that the toy car lands on it?

6.) A stunt car traveling at 20 m/s flies horizontally off a cliff and lands 39.2 m from the base of the cliff. How tall is the cliff?

7.) A blow dart is fired horizontally from a height of 1.2 meters. If the dart hits a target that is 0.6 m high and 12 m away, what is the initial velocity of the dart?

8.) A B-52 bomber jet flies at a horizontal velocity of 286.2 m/s and at an altitude of 7500 m above the ground. How far away horizontally should a payload be dropped to land on a target?

Somebody please help me... I'm so confused. If you do these questions, please include the steps and charts if there are any. I really need help. Thank you! Love ya!

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
