Use the worked example above to help you solve this problem. A ball is thrown upward from the top of a building at an angle of 30.0? to the horizontal and with an initial speed of 16.0m/s. The point of release is h=46.0m above the ground. (a) How long does it take for the ball to hit the ground? w Your response differs from the correct answer by more than 10%. Double check your calculations. S (b) Find the ball's speed at impact. m/s (c) Find the horizontal range of the ball. m EXERCISE HINTS: GETTING STARTED I I'M STUCK! Suppose the ball is thrown from the same height as in the PRACTICE IT problem at an angle of 34.0? below the horizontal. If it strikes the ground 44.4m away, find the following. (Hint: For part (a), use the equation for the x-displacement to eliminate v0?t from the equation for the y-displacement.) (a) the time of flight S (b) the initial speed m/s (c) the speed and angle of the velocity vector with respect to the horizontal at impact speed m/s angle - below the horizontal
