1. Hanging from the rear view mirror of your car is a plastic soccer ball. The ball is hanging from a single, massless string. While making a right turn at 45 mph you notice that the angle the ball and string make from the vertical is precisely 33 degrees.
(a) Illustrate and fully label the situation described above.
(b) Construct and fully label the necessary FBD (full body diagram) to help solve the problem.
(c) Determine the radius of the circular path of the soccer ball
(d) What is the mechanical force acting as the centripetal force on the following entities:
-Soccer ball
-The car
-The driver (Ignore any frictional forces that are acting on the driver)

A Ping-Pong ball hangs from a string that is attached to the rear view mirror of a parked car. The driver side window is open, and the passenger side window is closed. A strong breeze blows along the driver side of the car. What happens to the Ping-Pong ball? Assume the breeze is laminar and that Bernoulli’s equation applies. A Ping-Pong ball hangs from a string that is attached to the rear view mirror of a parked car (see A...
* This is all the information given QUESTION 1 (iii,iv) PLEASE!!!: Examine the car performance when the angle of both the front and rear wings is set to θ = 10◦. In all the analysis that follows ignore frictional losses other than drag. Determine: (iii) What is the maximum speed the vehicle can safely corner a bend with R = 30 m (ans. 108Km/hr). What is the power required at this speed? (ans. 27.8KW) (iv) What is the maximum speed...

ECE Review Worksheet 1 AP Physics Mr. Marrash 1. A space traveler weighs 980 N on Earth. What will the traveler weight on another planet whose radius is 3 times that of the Earth and whose mass is also 9 times that of the Earth. Do not use any numerical values of the universal gravitational constant G, the mass of Earth, or the radius of Earth to get your answer. 2. Two skaters, a man and a woman, are standing...
