Just for fun, a golfer throws a golf ball horizontally through the air and watches it bounce again and again down a long straight concrete path. the ball is thrown horizontally from a height of h0 = 1.5 m with an initial speed of v0 = 28 m/s. the coefficient of restitution between the golf ball and the concrete is e = 0.92. (a) determine the maximum vertical height the golf ball will reach after its third bounce, h3. (b) determine a formula for the maximum vertical height the golf ball will reach after its nth bounce, hn, in terms of the variables, h0, g, e, and n. (c) the bouncing of a small sphere is modeled as dynamic particle motion. particles are assumed to be point masses that take up no space, even though the diameter of a golf ball is about 42.7 mm in reality. eventually, after enough bounces have occurred, the golf ball will cease bouncing and roll along the ground. if we suppose that rolling begins when the bounce height drops to half the sphere’s true diameter, after how many bounces, m, will rolling begin?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
