A rescue helicopter drops a crate of supplies from a height of 160 feet. After t seconds, the crate is 160 - 16t^2 feet above the ground.
a) Find the velcocity of the crate at t=1
b) With what velocity does the crate strike the ground?
for a do i just find the derivative and plug 1 in for t?

velocity is dh/dt, so yes on a)
Now, for b, find t when h=0 Put that t into the dh/dt equation to find velocity.
