-A model rocket is launched from ground level. Its height, h meters above the ground, is a function of time t seconds after launch and is given by the equation h = -4.9t^2 + 65.6t. What would be the maximum height, to the nearest meter, attained by the model?

take the derivative of the funtion :

dh/dt = -9..8h+65.6

set the derivative equal to zero

so 9.8h=65.6 => h= 6.69 units
