(a) You throw a beach ball upward with an initial velocity of v0. When the air resistance is linear Fdrag = -bv, find the maximum height of the ball, the time of flight, and the final velocity. (b) You throw a beach ball upward with an initial velocity of v0. When the air resistance is quadratic Fdrag = -cv^2, find the maximum height of the ball, the time of flight, and the final velocity. (c) You throw a beach ball...

You throw a ball towards a wall at a speed of 20 m/s and at an angle of 50 degrees. The wall is 22 m away from you. (a) How far above the release point does the ball hit the wall? (b) What is the vertical component of the balls velocity when it hits the wall? (c) What is the horizontal component of the balls velocity when it hits the wall?

A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof a time of 1.20 s later. You may ignore air resistance. A) If the height of the building is 20.7 m , what must the initial speed be of the first ball if both are to hit the ground at the same time? B) Consider the same situation, but now let the initial speed v0 of the...

A baseball is thrown from the roof of 23.5 m -tall building with an initial velocity of magnitude 10.5 m/s and directed at an angle of 52.4° above the horizontal. What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance. What is the answer if the initial velocity is at an angle of 52.4° below the horizontal? If the effects of air resistance are included, will part (a) or (b)...

A carpenter tosses a shingle horizontally off a roof at an initial velocity u = 17m/s.

A carpenter tosses a shingle horizontally off a roof at an initial velocity u = 17m/s. The shingle travels a distance d = 20.0 m in the horizontal direction. You may assume that the acceleration Je to gravity is 9.8 m/s^2. Draw a vertical position vs. horizontal position (y vs. x) plot. Label the known Quantities in the plot. How long does it take the shingle to reach the ground? What is the height of the roof that the shingle...

3: Consider trying to hurl a bowling ball up onto the roof of a nearby building (while on planet Earth). The roof is 5 meters above the ground and 10 meters away from you. a. If you launch the bowling ball from the ground at a 45 degree angle, what is minimum launch velocity you need to get it onto the roof? Draw a diagram of the trajectory needed to get the ball onto the roof. b. If you increase...
