| **The lift rises with an acceleration of 2 s / s2, the acceleration vector is directed vertically upward. There is a body weighing 1 kg in the elevator. What is body weight?**

Given:

a = 2 meters per second squared – the acceleration with which the lift rises;

m = 1 kilogram – body weight in the elevator;

g = 10 meters per second squared – gravitational acceleration (constant near the Earth’s surface).

It is required to determine P (Newton) – the weight of the body in the elevator.

Since, according to the condition of the problem, the acceleration of the elevator is directed vertically upward:

P = m * (g + a) = 1 * (10 + 2) = 1 * 12 = 12 Newtons.

Answer: the weight of the body in an elevator moving vertically upwards will be equal to 12 Newtons.
