A 140 g, 90.0 mph fastball comes across the plate very nearly horizontally and is batted at 90.0 mph at a 30.0 degree angle (above the horizontal) toward center field.
(a) Determine the impulse (in N's) acting on the ball.
(b) If the impact time is 0.00080 s, determine the average force on the ball.
(c) The force on the ball as a function of time can be modeled as F(t) = Fmax sin^2(4000t). Using this function, assuming it will give the same impulse as the average force, find Fmax.
(d) Find the average acceleration of the ball.
(e) For some extra 2-D motion practice, does this ball clear the outfield fence, 410 ft away?
A force platform is a tool used to analyze the performance of athletes measuring the vertical force that the athlete exerts on the ground as a function of time. With what speed did she reach the platform
A Hall probe uses the Hall effect to measure the size of magnetic fields - it does this by measuring the potential difference across the electric field created by the displacement of charge
