A monkey weighs 6.00 x 102 N and swings from vine to vine. As the monkey grabs a new vine, both vines make an angle of 35.0° wit
natka813 [3]

To solve this problem we will apply the considerations of equilibrium on a body, we will decompose the tensions into their respective components and apply the sum of forces and solving equations for the given system.

According to the graph, the sum of the horizontal components would be

\sum T_x = 0

TSin35\° -TSin35\° = 0

0 = 0

The sum of the vertical components is

\sum T_y = 0

2TCos35\° - mg = 0

2TCos35\° = 600N

T = \frac{600N}{2Cos35\°}

T = 366.2N

Therefore the net force on the new vine is 366.2N

Find the components of vtot along the x and y axes in Figure 3.25, where = 23.0° and vtot = 7.56 m/s.
Romashka [77]

The component of the total velocity in the x - direction is 6.96 m/s.

The component of the total velocity in the y - direction is 2.95 m/s.

<h3>Component of the velocity in x direction </h3>

The component of the total velocity in the x - direction is calculated as follows;

v(x) = vtot cosθ

where;

  • vtot is total velocity
  • v(x) is velocity in x direction

v(x) = 7.56 x cos(23)

v(x) = 6.96 m/s

<h3>Component of the velocity in y - direction</h3>

v(y) = vtot sinθ

v(y) = 7.56 x sin(23)

v(y) = 2.95 m/s
