Question

The tension in a string from which a 6 kg
object is suspended in an elevator is equal to 61 N.
What is magnitude of the acceleration a of the elevator? The acceleration of gravity is
9.8 m/s^2.
Answer in units of m/s^2
61 N up
6*9.8 = 58.8 down
net force on object = 2.2 N up

F = m a
2.2 = 6 a
a = 2.2/6 = .367 m/s^2
