Ahome run is hit in such a way that the baseball just clears a wall 20.0 m high, located 114 m from home plate. the ball is hit at an angle of 33.0° to the horizontal, and air resistance is negligible. (assume that the ball is hit at a height of 1.0 m above the ground.) (a) find the initial speed of the ball. incorrect: your answer is incorrect. write the expressions for the horizontal and vertical positions as functions of time. then use the equations to find the initial speed and the time when the baseball reaches the height of interest. m/s

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
