Answer:
It will take 1.789 sec
Explanation:
We have given height h = 30 m
Initial velocity u = 8 m/SEC
Acceleration due to gravity
Now according to second equation of motion
After solving we get t = -3.42 sec and t = 1.789 sec
As negative time is not possible so time will be 1.789 sec
Distance is the physical length travelled. While the displacement is the shorter distance between any two given points.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two objects or locations.
Distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Displacement is defined as the shortest distance between the two points.
Sam determines the distance by doing the calculation as;
distance = speed × time
Hence, the Sam determines the distance and displacement by the respective formulas.
