Projectile Motion
Example 2
What does the equation h(t) = -16t2 + 32t + 48 say about the projectile?Step 1. Determine the initial height of the object and its initial velocity.
The initial height, s, is 48 feet. The initial velocity, v, is 32 ft/sec.
Step 2. State what these values represent.
The -16 shows that gravity pulls the object downward. The object is being thrown or projected at a velocity of 32 ft/sec. The object is thrown from a height of 48 ft.
