"Constant velocity" means zero acceleration, which means zero net force. So there must be100N pulling on the crate to cancel the 100N of friction force.
<span>B is the right answer. Global warming is caused by carbon dioxide and water vapor which are not air pollution. Indeed most air pollution counteracts global warming by reflecting sunlight.</span>
Answer:
14,653 J.
Explanation:
We know that,
Total mechanical energy is equal to the sum of all the potential and kinetic energies.
Given,
Kinetic energy when a car jumps off a ramp= 5000 J
Potential energy = 4685 J
Potential energy when the car lands= 4968 J
TME = 5000 + 4685 + 4968
= 14,653 J
Hence, the car's total mechanical engery is equal to 14,653 J.
