Answer:
When two objects in motion hit each other they experience forces that are equal in magnitude and opposite in direction. This force causes one of the objects to speed up or gain momentum and other to slow down or lose momentum.
Answer:
21 m/s
Explanation:
There are three forces on the pendulum:
Weight force mg pulling down,
Vertical tension component Tᵧ pulling up,
and horizontal tension component Tₓ pulling towards the center of the curve.
Sum of forces in the y direction:
∑F = ma
Tᵧ − mg = 0
T cos 37° = mg
T = mg / cos 37°
Sum of forces in the centripetal direction:
∑F = ma
Tₓ = mv²/r
T sin 37° = mv²/r
(mg / cos 37°) sin 37° = mv²/r
g tan 37° = v²/r
v = √(gr tan 37°)
v = √(9.8 m/s² × 60 m × tan 37°)
v = 21 m/s
Answer:
Units named after scientists are written in lowercase but their symbols are written as capital
Unit of power is watt, since it is named after a scientist, then symbol will be written as W
Farad, symbol = F
Henry, symbol = H
Units whose names aren't culled from that of scientists are written in lower case and their symbols are also in lower case.
Units such as meter, kilogram should be represented with symbols in small letters as: m and kg respectively.
