Based on the calculations, the kinetic energy of the model rocket at this point is equal to: A. 7,200 Joules.
Given the following data:
Mass = 1 kg.
Height = 500 m.
Velocity = 120 m/s.
How to calculate kinetic energy?
Mathematically, kinetic energy can be calculated by using this formula:
K.E = 1/2 × mv²
Where:
- K.E is the kinetic energy.
Substituting the given parameters into the formula, we have;
K.E = 1/2 × 1 × (120)²
K.E = 1/2 × 1 × 14,400
K.E = 7,200 Joules.
