6. You throw a ball out of a window at 4 m/s at a downward 30° angle. As a result, it takes 1.5 seconds for the ball to hit the ground. 30 A. How far does this ball travel horizontally before hitting the ground? (5.2 m) B. How high is this window from the ground? C. What is the velocity of this ball just before it hits the ground? Report your answer using components, or calculate the magnitude and direction.

Question 1 10 pts A ball is thrown directly downward at a speed of 3.6 m/s off the top of Building 15 at TCC. The ball passes the classroom we are not in 3.8 meters below the top of the building on its way down to the sidewalk below. The ball hits the ground with a speed of 18.2 m/s. Assume "up" is positive. What is the speed of the ball in m/s as it passes the classroom we could...

A pitcher throws a 0.143-kg baseball toward the batter so that it crosses home plate horizontally and has a speed of 42 m/s just before it makes contact with the bat. The batter then hits the ball straight back at the pitcher with a speed of 51 m/s. Assume the ball travels along the same line leaving the bat as it followed before contacting the bat. (a) What is the magnitude of the impulse delivered by the bat to the...
