An object of mass 800g hangs on a spring.Calculate the force exerted by the object if acceleration due to gravity is 10meters per second square

Sagot :

Ardni313idn

The force exerted : 8 N

Further explanation

Given

mass = 800 g

Acceleration = 10 m/s²

Required

The force exerted

Solution

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  

∑F = m. a  

[tex]\large {\boxed {\bold {a = \frac {\sum F} {m}}}[/tex]

F = force, N  

m = mass = kg  

a = acceleration due to gravity, m / s²  

Input the value :

F = 0.8 kg x 10 m/s²

F = 8 N
