What force is required to give an object with mass 50 kg an acceleration of 8 m/s2 O A. 6.25 N O B. 58 N O C, 400 N O D, 250 N

C, 400 N

Explanation:

Given parameters:

Mass of object  = 50kg

Acceleration  = 8m/s²

Unknown:

Amount of force  = ?

Solution:

According to Newton's second law of motion;

       Force  = m a

m is the mass

a is the acceleration

 Now insert the parameters and solve;

   Force  = 50  x  8  = 400N

if you answer my question i will answer yours

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
