Question

An object with a mass of 90 kg is placed on an orange tree branch 20.0 meters above the ground. The object moves with a velocity of 60 m/s. Calculate the kinetic energy and the potential energy of the object.

Answer 1

The kinetic energy of the object is 162,000 Joules, and the potential energy of the object is 17,640 Joules.

Step-by-step explanation:

To calculate the kinetic energy of the object, we can use the formula KE = 0.5 * mass * velocity^2. Plugging in the values, KE = 0.5 * 90 kg * (60 m/s)^2 = 162,000 Joules.

The potential energy of the object can be calculated using the formula PE = mass * acceleration due to gravity * height. Plugging in the values, PE = 90 kg * 9.8 m/s^2 * 20.0 m = 17,640 Joules.
