Answer:
Approximately along the slope, assuming that no energy was lost to friction.
Explanation:
Let denote the initial velocity of this vehicle. Let denote the mass of this vehicle. The kinetic energy (KE) of this vehicle would have initially been:
.
The gain in the gravitational potential energy (GPE) of this vehicle is proportional to the increase in its height.
Let denote the gravitational field strength. on the earth. If the increase in the height of this vehicle is , this vehicle would have gained GPE:
.
Hence, the height of this vehicle is maximal when the GPE of this vehicle is maximized.
Since the vehicle went out of fuel, all its GPE would have been converted from KE. Assuming that no energy was converted to friction. The GPE of this vehicle would be maximal when the entirety of the KE was converted to GPE.
Hence, the maximal GPE of this vehicle would be equal to its initial KE:
.
The maximum height of this vehicle would be:
.
Given that , the maximum height of this vehicle would be:
.
Refer to the diagram attached. The distance that this vehicle traveled along the slope would be approximately:
.
I believe it is B! Also I am just typing this stuff because it needs to be 20 characters long for some reason! Hope this helps!
Answer:
The net force acting on that object must be 0
Explanation:
According to Newton's first law of motion, if there's no force acting on an object (or the net force is 0), that object will stay at the same speed. That object acceleration must also be 0.
Answer:
Metals produce electrons ( photoelectrons ) when exposed to light.
Explanation:
These photoelectrons produce photocurrent and this was proved by Eistein illustration of photocurrent and stopping potential.
Answer: Find the answer in the explanation
Explanation:
The music playing on the radio will be heard through the sound waves coming from the radio.
The travelling wave will obey Newton's first law of motion which state that:
An object or particle will remain at rest or continue its linear motion in a straight line except an external force is applied.
The external force through wind could affect the travelling of the sound waves. Since the wave is longitudinal wave. That is, it needs a medium (air) for its propagation.
