A ball weighing 60 N is swinging like a pendulum at the end of a 6.0 m rope. As the ball swings through its lowest point, its speed is measured at 5.0 m/s. What is the tension in the rope at this point?
A. 58.6 N
B. 85.4 N
C. 90.2 N
D. 97.3 N
Answers: 3
(1)
- Tension in the rope, measured in newtons.
- Weight, measured in newtons.
- Gravitational acceleration, measured in meters per square second.
- Speed of the ball, measured in meters per second.
- Length of the rope, measured in meters.
, 
, 
and 
, then the tension in the rope at this point is:
![T = (60\,N)\cdot \left[1+\frac{\left(5\,\frac{m}{s} \right)^{2}}{\left(9.807\,\frac{m}{s^{2}} \right)\cdot (6\,m)} \right]](/tpl/images/1009/5697/7e8b0.png)
