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:
.

Answer:
a) Mat swum 100 meters.
b)after 4 length , Mat's displacement is zero.
Explanation:
As given, Mat and David are training for the swimming team , and Length of 1 side of the pool is 25 meter.
As swimming pool will be a cube or a cuboid , so it has only 4 sides.
a)
1 length = 23 meter
⇒4 length = 4×25 = 100 meter
So, Mat swam 100 meters.
b)
As after swam 4 lengths of the pool, Mat reaches to its initial position i.e Mat come back to its starting point.
As Displacement is always measures from the starting point.
So, after 4 length , Mat's displacement is zero.
Answer:
All electromagnetic waves travel at the same speed in a vacuum
Explanation:
All the wave listed in the question are electromagnetic waves. The speed of electromagnetic waves (collectively called light) in a vacuum is fixed. Its value is 3×10^8 ms^-1. This is a constant for all electromagnetic waves irrespective of their frequency.
Hence for any electromagnetic wave, its speed is 3×10^8 ms^-1, this will be the common velocity of all the electromagnetic waves listed in the question in a vacuum thus we can not rank them according to speed.
