Consider the static equilibrium diagram here. what is the angle f1 must make with the horizontal? a. 35º b. 49º c. 52º d. 59º e. 70º

ANSWER

EXPLANATION

Since the body is in equilibrium, total upward forces must equal total downward force.

Also the net horizontal forces acting on the body must be zero.

We need to resolve into vertical and horizontal components.

The horizontal component is

.

The vertical component is

.

Equating the up force to the downward forces gives,

.

This implies that,

.

Also the horizontal forces must be equal.

.

Dividing equation (1) by equation (2) gives,

.

.

Therefore the given angle that must make with the horizontal is approximately 35° to the nearest degree.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
