Question

Тіло масою 80 кг знаходиться в ліфті. Знайдіть його вагу , якшо ліфт маючи прискорення 2м/с2 рухається вгору

Answer 1

Дано:
m=80 кг
а=2м/с2
g=9,8м/с2
знайти:
Р
Р=m(g+a)
P=80*(9.8+2)=80*11.8=944Н

Answer 2

Calculation of Weight in an Elevator

To find the weight of a body in an elevator, we need to consider the acceleration of the elevator. In this case, the elevator is moving upward with an acceleration of 2 m/s^2.

The weight of an object is the force exerted on it due to gravity. It is given by the formula:

Weight = mass x acceleration due to gravity

The acceleration due to gravity is approximately 9.8 m/s^2.

Given that the mass of the body is 80 kg, we can calculate its weight as follows:

Weight = mass x acceleration due to gravity

Weight = 80 kg x 9.8 m/s^2

Weight = 784 N

Therefore, the weight of the body in the elevator, when it is moving upward with an acceleration of 2 m/s^2, is 784 Newtons (N).
