An 80 kg worker stands on a bathroom scale in a motionless elevator. When the elevator begins to move, the scale reads 960 N. Find the magnitude of the elevator's acceleration. (Use g=10m/s^2)

Explanation:

Given that,

Mass of a worker, m = 80 kg

When the elevator begins to move, the scale reads 960 N

We need to find the magnitude of the elevator's acceleration. The net force acting on it is given by :

So, the magnitude of the elevator's acceleration is .

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
