Answer:
120J
Explanation:
Given parameters:
Mass of the body = 0.6kg
Speed = 20m/s
Unknown:
Potential energy at maximum height = ?
Solution:
The potential energy at maximum height is equal to the kinetic energy that the body has gained.
Kinetic energy = mv²
Kinetic energy = x 0.6 x 20² = 120J
At the maximum height, the potential energy will be 120J
Answer:
Explanation:
The sandpaper block did not move because the forces of friction and gravity were balanced.
Proton only. That’s the answer
