A projectile is launched straight up in the air. Its height (in feet) t seconds after launch is given by the function f(t)=−16t2+378t+8. Find the time when it strikes the ground.
Added by Katie M.
Step 1
Step 1:** Set the height function equal to zero to find the time when the projectile strikes the ground: \[ -16t^2 + 378t + 8 = 0 \] ** Show more…

A projectile is launched straight up in the air. Its height (in feet) t seconds after launch is given by the function f(t)=−16t^2+408t+8. Find its average height from 4.1 seconds to 12.7 seconds. Round to two decimal places if needed

A projectile is launched from ground level with an initial velocity of v0 feet per second. Neglecting air resistance, its height in feet t seconds after launch is given by s= -16t^2 +v0t. Find the time(s) that the projectile will (a) reach a height of 64 ft and (b) return to the ground when v0=80 feet per second

Velocity functions A projectile is fired vertically upward into the air, and its position (in feet) abous the ground after $t$ seconds is given by the function $s(t)$ a. For the following functions $s(t)$. find the instantaneous velocity function $v(t) .$ (Recall that the velocity function $v$ is the derivative of the position function $s$ ) Determine the instantancous velocity of the projectile at $t=1$ and $t=2$ seconds. Evaluate $\frac{d s}{d t}$ and $\left.\frac{d s}{d t}\right|_{t=-1}$ if $s=11 t^{3}+t+1$
