The end of a diving board can oscillate with a frequency of 2.9 Hz. Assume it behaves like a simple harmonic oscillator in what follows. Before we deal with the diving board, first consider you have a mass, ?m, on a spring with spring constant, ?, oscillating with a certain frequency, ? and amplitude, ?. Derive an equation for ... a) the magnitude of the maximum speed of the oscillator in terms of the frequency, ? and the amplitude of...
2. A diver bounces straight up from a diving board, avoiding the diving board on the way down, and falls feet first into a pool. She starts with a velocity of 4.00 m/s upward, and her takeoff point is 1.80 m above the pool. (a) What is her highest point above the board? (b) How long a time are her feet in the air? (c) What is her velocity when her feet hit the water?
Can someone please help with 1) part A of top and 2) part B of bottom? Can't seem to get them! Part a A 0.561-kg ball is hung vertically from a spring. The spring stretches by 5.38 cm from its natural length when the ball is hanging at equilibrium. A child comes along and pulls the ball down an additional 5cm, then lets go. How long (in seconds) will t take the ball to swing up and down exactly 4...
Use column 2 (8 Kilometer data). Only need "f" and "g" please show work, thank you. Q2. In their paper "The Rewards to running: Prize structure and performance in professional road racing", Lynch and Zaxlook at whether races with large prizes record faster times because they attract faster runners, or because they encourage all runners to run faster (the paper can be found on D2L, but you shouldn't need to read it in order to answer this question) They regress...
