Question

An object with mass 3 kg is moving with a speed of 5 m/s at a height of 2.5 m above the ground. Using the ground as the “y=0m” point, what is the total mechanical energy of the particle, in Joules, J?

Expert Solution

Step 1

Given data

The object's mass is: m = 3 kg

The objects's speed is: v = 5 m/s

The height of the object is: h = 2.5 m

The expression for the total mechanical energy of the particle is given as:

$M E = P E + K E M E = m g h + \frac{1}{2} m v^{2}$

Here PE is the potential energy, and KE is the kinetic energy.
