F = m a
25982 - m g = ma
25982 = 2123 (a + 9.81)
The cable supporting a 2123 kg elevator has a maximum strength of 25982 N. What maximum upward acceleration can it give the elevator without breaking?
Can someone give me step by step on how to solve this?

A car starts from rest and travels for 6.0 s with a uniform acceleration of +1.5 m/s2. The driver then applies the brakes, causing a uniform acceleration of -2.0 m/s2. If the brakes are applied for 3.0 s, how fast is the car going at the end of the braking period?

Hey Damon, i'm not sure if i calculated wrong, but was I supposed to do
(2123)(9.81a) = 20826.63a
then divide 25982a/20826.63?
(2123)(9.81a) = 20826.63a
then divide 25982a/20826.63?
Oh, nvm haha I'm an idiot. I got it THANKS A BUNCH!
