Question

A model rocket is launched straight upward. Its altitude yy as a function of time is given by y=bt−ct2y=bt−ct2, where bb = 81 m/sm/s , cc = 4.9 m/s2m/s2 , tt is the time in seconds, and yy is in meters. Use differentiation to find a general expression for the rocket's velocity as a function of time.

Step 1

The altitude \( y \) as a function of time \( t \) is given by the equation: \[ y = bt - ct^2 \] where \( b = 81 \, \text{m/s} \) and \( c = 4.9 \, \text{m/s}^2 \). Show more…
