A student kicks a soccer ball with an initial velocity of 12.0 m/s at a fence at an angle θ = 53 degrees, which is a height 3.5 meters and is a distance of 5.0 meters away from where they kicked the ball. The ball hits nothing in flight while in flight and air resistance is negligible.
sin 53 degrees = 0.80
cos 53 degrees = 0.60
tan 53 degrees = 1.33
A. Determine the initial horizontal and vertical velocity vox and voy of the ball.
B. Determine the time it takes for the ball to reach the fence.
C. Will the ball hit the fence? If so, how far below the top of the fence will it hit? If not, how far above the top of the fence will it pass?
D. The student repeats the kick in a flat field with no fence, it lands at the same vertical
position it was kicked from.
i. How much time does the ball spend in the air?
Ii. Determine the horizontal distance the ball will travel.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply. the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
