Question

An elevator filled with passengers has a mass of 1600 kg. What is the force exerted by the elevator floor when accelerating upward at 2 m/s^2?

a) 3200 N
b) 1600 N
c) 4800 N
d) 800 N

Answer 1

The force exerted by the elevator floor when accelerating upward at 2 m/s^2 is 3200 N.

Step-by-step explanation:

When an elevator is accelerating, the force exerted by the elevator floor is equal to the product of the mass of the elevator and the acceleration.

In this case, the elevator has a mass of 1600 kg and is accelerating upward at 2 m/s^2. So, the force exerted by the elevator floor is:

Force = mass x acceleration

Force = 1600 kg x 2 m/s^2

Force = 3200 N

Therefore, the correct answer is a) 3200 N.
