The lift moves vertically upward with an acceleration of 2 m / s2. Determine the weight of the boy at this moment, the weight of the boy is 50 kg.

Initial data: a (acceleration with which the lift moves vertically upwards) = 2 m / s2; m (boy’s weight) = 50 kg.

Reference values: g (acceleration due to gravity) = 10 m / s2.

The weight of the boy, at the moment when the lift moves up, can be calculated by the formula: P = m * (g + a).

Let’s calculate: P = 50 * (10 + 2) = 50 * 12 = 600 N.

Answer: d) The boy’s weight will be 600 N.
