The work done to a 300 gram baseball as it is hit is equal to 1800 J. When the ball is hit, 200 J
of energy is released as sound energy (not KE). The ball is hit at a 30° angle into the air and
travels as a projectile. For 5 bonus points, calculate the initial velocity of the ball as it leaves the
bat. For another 5 points, find the gravitational potential energy of the baseball when it reaches
the highest point in its flight (ignore air resistance)? You may need to incorporate what we know
about projectile motion.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
