Question

A 0.5 kg ball is suspended from a ceiling by two strings

A) The tension in each string is 0.25 N
B) The tension in each string is 0.5 N
C) The tension in each string is 1 N
D) The tension in each string is 2 N

Answer 1

The tension in the rope when the elevator accelerates upward at 1.5 m/s² is 22.6 N, while the tension in the rope when the elevator accelerates downward at 1.5 m/s² is 16.6 N.

Step-by-step explanation:

The tension in the rope when the elevator accelerates upward at 1.5 m/s² is 22.6 N, while the tension in the rope when the elevator accelerates downward at 1.5 m/s² is 16.6 N.

When the elevator accelerates upward, the tension in the rope increases because the force required to accelerate the mass upward is greater than the force of gravity pulling it downward. When the elevator accelerates downward, the tension in the rope decreases because the force required to accelerate the mass downward is less than the force of gravity pulling it downward.
