Answer:
A light year is a measure of distance as opposed to a time measurement. This is because a light year is the distance light can travel in the time of a year.
They will hit the ground at the same time, as mass is negligible when calculating the acceleration of gravity when there is no air resistance
Answer:
Average speed
meter per second
Explanation:
Given
The total distance walked
meters
The total time taken to walk
meters is
minutes
In one minute there are
seconds
As we know Average speed is equal to total distance travelled divided by total time taken
Hence,
Average speed
meter per second
