Use Newton's 2nd law of motion.
Here it is:
Force = (mass) x (acceleration)
= (80 kg) x (-5 m/s²)
= -400 Newtons .
I called the acceleration negative because the player is slowing down.
The force comes out negative because it's in the direction opposite to
his motion.
Answer: A, a polished pale yellow surface would likely be the best reflector of heat energy.
Answer:
The answer to the question is highlighted in the box
Answer:
4/3 pi R^3 = pi r^2 L equating volume of sphere and wire
r = (4 R^3 / 3 * L)^1/2 solving for radius of wire
r = (4 * 6^3 / 3 * 32)^1/2
r = 9^1/2 cm = 3 cm = .03 meters
