Question

A 58-kg person is being pulled away from a burning building as shown in the figure above.

Calculate the tension in the two ropes if the person is momentarily motionless.

Please answer the following question(s):
1.
15°
T1
T2
0.10°
A 58-kg person is being pulled away from a burning building as shown in the figure above.
(b) Calculate the tension in the two ropes if the person is momentarily motionless.
(i) Write expressions for Fnet x and Fnety in terms of T, T, m, g, and the numerical values of the
angles. Take the upward direction to be the +y-direction, and to the right to be the +x-direction.
Fill in the blanks below based on the components of the forces that contribute to Fnet.x and
Fnet,y"
Remember to put units of degrees on the angle using the degree symbol available in the
math type menu by clicking the arrow to the right of the division sign. For example you could
enter cos(32°).
Fnet.x =
V T, +
V mg =0
Fnet,y =
V T, +
V T2 +
V mg =0
(ii) Compute the numeric values of the tensions T, and T,.
T2 =
