Question

The mass of lift is 2000 kg. When the tension in the supporting cable is 30,000 N, then its acceleration is:

Answer 1

Answer:

A= F/ M

30000/2000

so answer is 15...

Answer 2

Given : mass = 2000kg

            force = 30,000N

To find : acceleration of the mass.

Solution : Force is defined as the product of mass and acceleration. It is defined according to the Newtons second law of motion. acceleration of any mass is depended on two variable , one is the net force and other is the mass of object.

Force = mass × acceleration

                   30,000N = 2000kg × acceleration

                                a = 30,000 / 2000

                                a = 15m/sec²

        acceleration of the mass = 15m/sec²
