A 593 N physics student stands on a bathroom scale in an 888

A 593 N physics student stands on a bathroom scale in an 888-kg (including the student) elevator that is supported by a cable. As the elevator starts moving, the scale reads 478 N . The magnitude of the acceleration of the elevator is 1.90 m/s^2.

What is the tension in the cable?

Solution

Tension in the cable

T=m(a+g) =888(1.9+9.8)

T=10,390 N or 10.39 KN
