Question

Дано: m=20кг h=1,5 км=1500м g=10н/кг Ep=?

Answer 1

Eп= mgh

Eп= 20кг×10н/кг × 1500м= 300000Дж= 300кДж

Answer 2

To calculate the gravitational potential energy (Ep) of an object, we can use the formula:

Ep = m * g * h

where: m = mass of the object (in kg) g = acceleration due to gravity (approximately 9.8 m/s^2 on Earth's surface, but you provided 10 N/kg) h = height above the reference point (in meters)

Given: m = 20 kg h = 1.5 km = 1500 m g = 10 N/kg

Now, let's calculate Ep:

Ep = 20 kg * 10 N/kg * 1500 m Ep = 300,000 Nm or 300,000 J (Joules)

So, the gravitational potential energy of the object is 300,000 Joules.
