Question: When an object is thrown straight upward, gravity causes it to decelerate at a rate of 1 g its speed decreases 9.8 m/s or 22

When an object is thrown straight upward, gravity causes it to decelerate at a rate of 1 g —its speed decreases 9.8 m/s or 22 mph each second.

(a) Explain how we can use the equations, tables, and graphs for a freely falling body to analyze this motion.

(b) A baseball is thrown vertically upward at a speed of 39.2 m/s (88 mph). How much time elapses before it reaches its highest point, and how high above the ground does it get?
