The body is thrown from the surface of the earth vertically upwards at a speed of 4 m / s. What is the maximum height from the surface it will rise?
Given:
V = 4 m / s
Find: h
Decision
E (n) = mgh
E (k) = mv ^ 2/2
mgh = mv ^ 2/2
h = v ^ 2 / 2g = 4 ^ 2 / (2 * 10) = 0.8 m
Answer: The thrown body will rise from the surface by 0.8 m
