Answer:
1760J
Step-by-step explanation:
Given parameters:
Mass of rock = 55kg
Velocity = 8m/s
Unknown:
Kinetic energy = ?
Solution:
The kinetic energy of a body is the energy to motion of a body.
K.E = [tex]\frac{1}{2}[/tex] m v²
where m is the mass and v is the velocity
Insert the parameters and solve;
K.E = [tex]\frac{1}{2}[/tex] x 55 x 8² = 1760J
