Glaunch to impact a ball, initially at rest and 1 meter above ground, is launched upward with a 500n force acting for 0.02 seconds. the ball flies vertically upward to a maximum height and falls back, sinking into the soft ground a distance of 2.0 cm. calculate the velocity after 0.01 seconds of force is applied, the maximum height if the force terminated when the ball was 2m above ground, the velocity of impact when it reached the ground and the average force exerted by the ground on the ball.

the force required to move the cart is divided by three or 33.33 n.

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
