Question

In the work energy equations in the y-direction the sin is usually ____, unless stated otherwise

a) 1
b) 0
c) 0.5
d) π

Answer 1

In the work energy equations in the y-direction, the sin is usually 0, unless stated otherwise.

Step-by-step explanation:

In the work energy equations in the y-direction, the sin is usually 0, unless stated otherwise. This is because the work done in the y-direction is determined by the component of the force acting in that direction, which is given by the sine of the angle between the force and the displacement.
