How fast is the arrow traveling when it hits the ground? Explain how you arrived at your answer.

(prior to that i found the time it takes for the arrow to reach the ground level a 5.0803s)

**drwls**, Monday, October 11, 2010 at 7:47amThe way to solve this is explained in your subject title. Compute the derivative of the function, which is the speed, and calculate its value at t = 5.0803 s.

The derivative is

V(t) = dh/dt = -9.8t + 24.5

Plug in the value of t that you got (which was correct) and compute V
