4 n to the right is the net force
Kinetic energy is the energy of an object that is moving. It is calculated from one-half the product of the mass and the change in square of the velocity of the object. It is the opposite of potential energy which the energy possessed by an object at rest. We calculate as follows:
KE = mΔv^2 / 2 = 45 ( 6^2 - 12^2 ) = -4860 J had been lost by the skater
I believe it is false because as the ball begins to fall and becomes more distant the speed will become slower
fiber-optic cable is composed of two concentric layers, called the core and the cladding, as illustrated in Figure 3-1. The core and cladding have different refractive indices, with the core having a refractive index of n1, and the cladding having a refractive index of n2. The index of refraction is a way of measuring the speed of light in a material. Light travels fastest in a vacuum. The actual speed of light in a vacuum is 300,000 kilometers per second, or 186,000 miles per second.
Answer:
Explanation:
Given
Required
The component of the force in F direction
To do this, we simply calculate the force in the vertical and horizontal direction.
This is calculated as:
--- Horizontal
---- Vertical
So, we have:
--- Horizontal
---- Vertical
