Answer:
the time taken for the object to fall is 6 s.
Explanation:
Given;
final velocity of the object, v = 58.8 m/s
initial velocity of the object, u = 0
The height of fall of the object is calculated as;
v² = u² + 2gh
v² = 2gh
The time to fall through the height is calculated as;
Therefore, the time taken for the object to fall is 6 s.
Answer:
Part A: The car shoots out of the milk carton at a fast speed.
Part B: Potential Energy
Part C:
1. Gravitational Potential Energy
2. Motion Energy
3. It goes from Motion Energy/Kinetic Energy to Gravitational Potential Energy.
4. Motion Energy
Part D: It is a transfer of energy from the rubber band to the car.
Part E: The car stopped because of gravitation pull that is slowly making the car slow down and eventually stop. The energy is then converted to kinetic energy and heat energy.
Part F: I would think adding force would make the car move again. The type of energy it would have while moving would be: Motion Energy.
Have a great day! :D
Answer: One thing magnetism and electricity have in common is that they are related.
Explanation: Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow.
