A springboard diver jumps up and comes back to the level of the board after 0.81 s. What was her speed as she leaves the board? How high (above the board) did she reach? A toy rocket stops accelerating when it reaches a height of 30 m. Its speed is 30 m/s at this point and continues upward. Take time to be zero at this point. (a) How fast is it moving when it is at a height of 40.0 m? (b) How much time is required from t = 0 to reach this height? (c) Why are there two answers to (b)?
