Question

m=1кг h1=20м h2=10м Ек1-? Ек2-?

Answer 1

Ответ:

To find the potential energy (Ek) of an object, we use the formula:

Ek = m * g * h

Where:

m = mass of the object (in kg)

g = acceleration due to gravity (approximately 9.8 m/s^2)

h = height (in meters)

Given:

m = 1 kg

h1 = 20 m

h2 = 10 m

For Ek1:

Ek1 = m * g * h1

= 1 kg * 9.8 m/s^2 * 20 m

= 196 J

For Ek2:

Ek2 = m * g * h2

= 1 kg * 9.8 m/s^2 * 10 m

= 98 J

Therefore, Ek1 is 196 Joules and Ek2 is 98 Joules.
