Three kids in a parking lot launch a rocket that rises into the air along a $380-\mathrm{m}$ long arc in $40 \mathrm{~s}$. Determine its average speed.
During the first $40 \mathrm{s}$ of a rocket flight, the rocket is propelled straight up so that in $t$ seconds it reaches a height of $s=0.3 t^{3} \mathrm{ft}$. (a) How high does the rocket travel in $40 \mathrm{s}$ ? (b) What is the average velocity of the rocket during the first $40 \mathrm{s}$ ? (c) What is the average velocity of the rocket during the first $1000 \mathrm{ft}$ of instight? (d) What is the instantancous velocity of the rocket at the end of $40 \mathrm{s} ?$
THE DERIVATIVE
Tangent Lines and Rates of Change
Use Formulas (2) and (3) to find the average and instantaneous velocity. During the first 40 s of a rocket flight, the rocket is propelled straight up so that in $t$ seconds it reaches a height of $s=5 t^{3} \mathrm{ft}$ (a) How high does the rocket travel in 40 s? (b) What is the average velocity of the rocket during the first $40 \mathrm{s} ?$ (c) What is the average velocity of the rocket during the first $135 \mathrm{ft}$ of its flight? (d) What is the instantaneous velocity of the rocket at the end of $40 \mathrm{s} ?$
