Answer to Question #266651 in Physics for Kiki

Question

A 6.61 kg pendulum hangs in an elevator. The tension in the string supporting the pendulum if the elevator moves upward with a constant acceleration of 2.41 m/s² is ab.c N [up]. Input the values of a, b and c into the blank and use the guidelines below:

• Do not include a positive or negative sign.
• Include a decimal in your answer.
• Use a acceleration value of 9.81 m/s²
• Let up be positive

Answer 1

The force of tension is

$$T=m(g+a)=80.7\text{ N}.$$
