What force must be applied to a body weighing 500 g so that it travels a distance of 20 m in 10 seconds?

univerkov | December 18, 2020 | education

Given:
m = 500g
t = 10s
S = 20m
V₀ = 0m / s (initial speed)
SI
m = 0.5kg
Find F =?
Decision:
V = S / t;
V = 20m / 10s = 2m / s;
a = (V-V₀) / t;
a = (2m / s-0m / s) / 10s = 0.2m / s squared
According to Newton’s second law
F = m * a
F = 0.5kg * 0.2m / s squared = 0.1H
Answer: F = 0.1H
