Please tell me if I have done this correctly.
A ball is thrown upward from the ground with an initial velocity of 10 m/s. Assume all digits are significant.
a. How long before the ball reaches its maximum height?
t = (0m/s - 10m/s) / -9.80m/s2 t = 1.0s
b. What is the ball's maximum height?
x = 0m + .5(10m/s + 0m/s) x = 5.0 m
c. What is the velocity of the ball when it returns to the ground?
v = 0m/s + -9.80m/s2 * 1.0s v = -9.8 m/s
