At a local swimming pool, the diving board is elevated h = 9.5 m above the pool's surface and overhangs the pool edge by l = 2 m. a diver runs horizontally along the diving board with a speed of v0 = 2.7 m/s and then falls into the pool. neglect air resistance. use a coordinate system with the horizontal x-axis pointing in the direction of the diver’s initial motion, and the vertical y-axis pointing up. let the y-axis be directed vertically down. express the time t_w it takes the diver to move off the end of the diving board to the pool surface in terms of v_0, h, l, and g. calculate the time, t_w in seconds, it takes the diver to move off the end of the diving board to the pool surface. determine the horizontal distance, d_w in meters, from the edge of the pool to where the diver enters the water.

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.

Aplayer uses a hockey stick to push a puck at a constant velocity across the ice. the weight of the puck is 170 n. the coefficient of friction is 0.0600. with what force must the player push the puck so that his force just equals the frictional force? 28.3 n 0.999 n 0.102 n 0.0104 n
