Question

A pole-vaulter clears a crossbar and takes 1.0 s to fall from the apex of his flight to the landing pit. What was his downward vertical velocity at the end of this second? 4.9 m/s 9.81 m/s 1.0 m/s 19.62 m/s If a body has an initial velocity of -20 m/s and it experiences an acceleration of -9.8 m/s2 for 2 s, which of the following statements is true? The magnitude of the velocity will increase. The direction of motion will be reversed. The displacement will be positive. The body will have a final velocity of 20 m/s. All of the above are true. A-Rod hits a baseball with a speed of 35 m/s at an angle of 55 degrees from the horizontal. Assuming that the ball is caught by a fielder at the same height that it left the bat, how far did the ball travel? Answer = m (so you don't have to include units in your answer - also, round to closest meter)
