Answer:
44J
Explanation:
Given parameters:
Mass of rock = 0.22kg
Initial velocity = 20m/s
Distance moved = 10m
Unknown:
Initial kinetic energy of the rock = ?
Solution:
To solve this problem, we need to understand that kinetic energy is the energy due to the motion of a body.
It is mathematically expressed as;
Kinetic energy = m v²
m is the mass
v is the velocity
Kinetic energy = x 0.22 x 20² = 44J
Hi there!
Recall the equation for work given a potential difference and charge:
W = Work (J)
q = charge (C)
V = Potential difference (V)
The work is equivalent to the change in KINETIC ENERGY, and only depends on the particle's charge and the potential difference that it experiences. Mass has no impact on this.
Thus:
This is equivalent to:
