Unformatted text preview: (d)Find the maximum height of the ball. 3. The launch tower for the space shullte is approximately 100m tall. It takes the shuttle about 5.00s to clear this tower. (a)Estimate the acceleration of the shuttle and state any simplifying assumptions you use. (b)Find the velocity of the shuttle as it clears the tower. Physics 4A FIRST EXAM Chapters 1 - 4 Spring 1999 3 4. A punter wants to kick a football so that it spends 4.00s in the air and travels 40.0m down the field. Find the horizontal and vertical components of initial velocity vector of the ball as it leaves the punter’s foot. 5. The moon orbits Earth every 27.4days. Find (a)the speed of the moon in its orbit and (b)the acceleration of the moon. (c)A rock dropped from your hand accelerates toward the center of Earth due to gravity. Does the moon accelerate due to gravity? If so, in what direction? The effect of gravity on the rock causes it to fall toward Earth. Why doesn’t the moon fall?...
