You throw a ball from your window 14 meters above the ground. When the ball leaves your hand, it is moving at a speed of 20 m/s at an angle of 10 degree below the horizontal. Choosing a coordinate system such that its origin is located on your hand, the positive x axis is down and the positive y axis is right. Calculate how far horizontally from your hand, the ball lands.

9. A 2-kg ball is dropped out of a w is dropped out of a window from a height of 12 meters (Point A). It hits the grow and bounces back up to a height of 8 meters above the ground (Point). a. What is the potential energy of the ball at points A and C b. What is the velocity of the ball just before and just after it hits the ground (points B and B')?...
A ball is thrown up 90 feet in the air. it comes down, bounces, and then rises up to a height of 81 feet. Then it falls to its second bounce, and so on. Each time it falls, it bounces back to 90% of its previous height. (a) How high does the ball rise before the 30th bounce? (Please read the question carefully. If the question read “How high does the ball rise before the second bounce?” the answer would...
(a) A ball is dropped from rest from an initial height h above the floor. It then bounces several times. Draw graphs the position y(e), velocity v, (e) and acceleration ay () of the ball for two complete bounces (hitting the ground t for py Ct) ay (t) (b) If the ball is released from rest at a height h the ground? 1.50 m above the floor, how fast is the ball moving when it reach (c) If the ball...
1. Recall the following scenario from a class activity: A ba is thrown (from the ground) to a height of 10 feet. It then falls and bounces repeatedly. After each bounce, it rises to of the previous height (a) Express the total vertical distance the ball travels until it stops (going up and down on each bounce) as a geometric series and compute its value using the short-cut formula for geometric series. Make sure to justify the geometric series you...
A ball is launched from the ground at an angle of 65∘ above the horizontal with a velocity of 22m/s. The ball hits the ground some distance away at a given speed, and bounces back up. When it does so the amplitude of both the x and y components of its velocity are half what they were. This repeats with the ball losing half of it’s speed on each bounce. a) Sketch the problem. [2 points b) Write the equation...
A ball is thrown upward from the ground. You observe the ball through a window on its way up, and notice that it was visible for 1 seconds while it travels from the bottom of the window to the top, which is a length of 17.805 metres. (a) How much time does it take for the ball to be seen again, in seconds? (b) How far above the top of the window will the ball reach, in metres?
You toss a ball from your window 14 meters above the ground. When the ball leaves your hand, it is moving at a speed of 20 m/s at an angle of 10 degree below the horizontal. Choosing a coordinate system such that its origin is located on your hand, the positive x axis is down and the positive y axis is right. Provide all the simplified equations of motion in both directions for this projectile motion problem.
A tennis ball is shot straight up from the ground. After traveling 4.00 m, the ball passes a 4.00 m high window and then continues straight up until it loses all its upward velocity and falls to the ground. During the last second of its flight before it hits the ground, the ball drops 20.0 m. a) What is the maximum height above the ground reached by the ball? b) What is the total time for the ball’s flight? c)...
