Jim Guinn’s PHYS2211 Assignment #5 These problems are not to be turned in. They are for your practice for the exam. (You’re welcome!) 1. While golfing, Haile hits a ball from the ground, at an angle of 12.0 o above the horizontal and an initial speed of 55.0m/s . Ignore air resistance. a.) How far horizontally does the ball fly before hitting the ground? b.) How high is the ball at its highest point? c.) What is the speed of the ball at its highest point? 2. Saba throws a stone off of a cliff with a speed of 25.0m/s at an angle of 10 o below the horizontal. She sees the stone hit the ground 3.00sec later. a.) How high is the cliff?

Unformatted text preview: 3. William throws a ball to Kyle. William throws the ball at 25.0m/s at an angle of 15.0 o above the horizontal. Kyle catches the ball 0.750m below the height that William threw it. a.) How far apart are William and Kyle? b.) How fast is the ball moving when Kyle catches it? 4. While playing basketball, Jhong makes a jump shot 5.50m horizontally from the basket, which is 3.05m above the floor. The ball leaves Jhong’s hands at a height of 2.00m and at an angle of 65.0 o up from the horizontal. With what speed should Jhong throw the ball in order for it to go in the basket? (Hint: using the horizontal motion, solve for the time in terms of the speed, v. Then solve the vertical motion. See the diagram below.) 65.0 o 5.50m 3.05m 2.00m...
