A ball is tossed straight up in the air with an initial velocity of 25 m/s. Answer the questions below assuming g = 10 m/s² downward. Assume an upward positive sign convention. a. What is the velocity of the ball at the top of the toss? b. What is the acceleration of the ball at the top of the toss (include the sign)? c. How long would it take for the ball to reach the top of its toss? d. If the ball were caught at a point 10 m below the height from which it was thrown, what would be its final velocity (just before it was caught).

8. A ball is tossed straight up in the air with an initial velocity of 25 m/s. Answer the questions below assuming g = 10 m/s² downward. Assume an
upward positive sign convention.
a. What is the velocity of the ball at the top of the toss?
b. What is the acceleration of the ball at the top of the toss
(include the sign)?
c. How long would it take for the ball to reach the top of its
toss?
d. If the ball were caught at a point 10 m below the height from
which it was thrown, what would be its final velocity (just
before it was caught).
