Kinetic energy because it is moving
The most common symbol for momentum is p
Answer:
T1 = 490.5 [N], T2 = 490.5[N]
Explanation:
First, we must draw a free body diagram of the steel ball hanging and the two wires holding it as well as the angle forming the wires between them.
The free-body diagram can be seen in the attached image.
As the cables are symmetrical with respect to the vertical axis, the force in cables 1 and 2 is equal, so when performing a force sum equal to zero on the Y-axis, we can find the force value of any cable.
The solution of the equations can be seen in the attached image
Answer:
4. Parabola
Explanation:
The motion of the flight of the grenade is a projectile motion, it's shape is best illustrated using a parabolic diagram.
It's not a circle as the path is not totally round.
It's not an ellipse as the path of motion is not a a completely bounded shape.
Its not a hyperbola as a hyperbola is an open curve with two branches.
Its a parabolic shape because a parabola has just one branch
Wood is typically an insulator(resists flow of electricity though it)
However, wet wood can be a conductor so really it depends
