A baseball player throws a 145g ball toward home-plate from the out-field. The throw was made at 30.0m/s, 30.0o above horizontal [South]. If the baseball player releases the ball 2.45m above the ground; a. Determine the velocity (speed and direction) at the moment the ball strikes the ‘turf’ (ground). b. Determine the time at which the ball possessed a minimal amount of kinetic energy. c. Determine minimum level of kinetic energy for the ball throughout its flight.
