A stunt driver leaps off a bridge 50 m above a river with an initial upward velocity of 10 m/s. Her altitude is given by h = -5t^2+10t+50, where t is in seconds and h is in meters.
c) Construct a table showing her average velocity during 1-second intervals starting at time 0
d) When does her velocity change from positive to negative?
e) What does this change represent?
f) When does she hit the water?
g) what is her avg speed in the half-second before she hits the river?
h) how would you find out the true avg speed between t=0 and t=2 seconds?
