A batter at petco park hits a fastball that leaves his bat with a speed of 26.5 m/s, if the ball leaves the bat at an angle of 30.0 with respect to the ground, how high does the ball get? how long is the ball in the air? what is the balls maximum horizontal distance? what is the balls speed when it hits the ground?

Asquare isothermal chip is of width w=5 mm on a side and is mounted in a substrate such that its side and back surfaces are well insulated; the front surface is exposed to the flow of a coolant at tinf=15 °c. from reliability considerations, the chip temperature must not exceed t=85 °c. if the coolant is air and the corresponding convection coefficient is h=200 w/m2 x k, what is the maximum allowable "power" of the chip? if the coolant is a liquid for which h=3000 w/m2 x k, what is the maximum allowable power of the chip?
