# Physics Newton law

A 10O0Kg elevator is hoisted upward from rest by a cable. In the first two seconds there is an 1100N tension force in the cable hoisting the elevator. What is the speed after two seconds and how far has it travelled ?

Get the acceleration first.

Tension=mg + m*acceleration.
solve for acceleration.
Then, vfinal=vinitial + acceleration*time

I didn't put numbers in as something is wrong with the mass (1000kg) or the force (1100N) numbers. A force of that magnitude wont support even a still elevator, much less move it upward.
Weight of elevator= mass*g...

Sorry it should have been 11000N. Yes i got the answer 2.4 m/s
