    Ball Diameter (mm)Time from photogate (s) 0.006 Instructions: A single photogate is programmed to start a timer when it is blocked, and stop the timer when it is unblocked A sphere with constant velocity passes through the photogate. Using the appropriate data in the table, determine the speed of the sphere as it passes through the photogate. Assume that the beam of the photogate is aligned such that the photogate will collect data based on the sphere's diameter. All work...

    You toss a ball from a balcony. When the ball leaves your hand, it is 10.0 meters above the ground and has a velocity of (10.0 m/s, 45.0 degrees above the horizontal). Ignore air resistance. (let's take the x-direction to be aligned with the horizontal motion and the y-axis to be upward.) A) How high above the ground does the ball go, and how much time does it take to reach max height? B) Determine the total time of flight....

    Allison throws a tennis ball at time t = 0 from a height h above the ground equal to her own height. We assume that the positive horizontal direction is the positive x-direction, and the positive vertical direction is the positive y-direction. The ball has a positive initial horizontal velocity vx, and no initial vertical velocity. At times t1 and t2, the ball bounces on the ground for the first, and second times respectively after being thrown. We assume that...
