You are standing on the top of a tall cliff and shoot an arrow from a height of 30.0 m at 25.0 m/s and an initial angle of 32c above the horizontal. Show all your work in calculating the answers to the following questions. You may check your work using any of the simulations you have used previously in Unit A.

a. What are the horizontal and vertical components of the arrow's initial speed?

b. How high above the base of the cliff will the arrow rise? Assume a level landscape.

c. How far off course will the arrow be after 3.35 s if there is a 12.0 m/s crosswind? Show all work.

d. What is the speed and angle of flight of the arrow 3.35 s after release if there is no crosswind?

Show all work.

the body's situation won't change the forces are equal opposit and on the same body

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
