Question 635730: a steel ballis dropped from a height of 5m on to a lake it hits the water surface and moves to the bottom of the lake. calculate the average velocity of the ball if the time for total jouney is 11seconds? Answer by ewatrrr(24785) (Show Source):
Hi,
a steel ball is dropped from a height of 5m on to a lake it hits the water surface in 11sec
calculate the average velocity
h = -16t^2 + vt + 5m
0 = -16(11)^2 + 11v + 5m |Solve for v
