Question

M=2кг h=1 ,5м найти A

Answer 1

F = mg A = Fh F = 2 кг × 10 Н/кг= 20 Н А = 20 Н × 1,5 м = 30 Дж Как-то так...:-)

Answer 2

To calculate the potential energy, A, of an object with mass (M) and height (h), you can use the formula:

A = M * g * h

Where: A is the potential energy. M is the mass of the object. g is the acceleration due to gravity (approximately 9.8 m/s² on Earth). h is the height.

Substituting the given values: M = 2 kg h = 1.5 m g = 9.8 m/s²

A = 2 kg * 9.8 m/s² * 1.5 m

Calculating the expression: A = 29.4 Joules

Therefore, the potential energy (A) of the object is 29.4 Joules.
