1. D = Vt = 3m/s + 10s = 30m.
2. h = (Vf^2 - Vo^2) / 2g,
h = (0 - (18)^2) / -19.6 = 16.53m.
3. d = Vo*t + 0.5g*t^2 = 35m.
0 + 4.9t^2 = 35,
t^2 = 7.14,
t = 2.67s.
A ball rolls along a desktop with an uniform velocity of 3 m/s. What is the displacement after 10 seconds have passed?
A ball is thrown upward with an initial velocity of 18 m/s? What is the maximum height the ball reaches if the ball is assumed to leave from the ground?
