Question

When calculating the effect of Earth’s gravitational pull on a launched projectile, the expression −16t2
is used to represent that the projectile falls at a rate of 16 feet per second squared. If a toy rocket is launched vertically upward from the ground at an initial velocity of 132 feet per second, does the equation −16t2+132t
properly model the height of the toy?

Type 1 for yes.
Type 2 for no.

Answer 1

1

Yes — s(t) = -16t^2 + 132t matches s0 = 0 and v0 = 132 ft/s (with gravity = -32 ft/s² → -16t² term).
