Question

(Newton's Law of Motion) A force of 20N acts on body whose weight is 8N. (a) What is the mass of the body? (b) What is its acceleration?

Answer 1

on earth divide wieght by gravitational acc.
8N/9.8m/s/s =.84kg
20N=0.84kg*a
a=23.75m/s/s

Answer 2

what's m/s/s? meter per second squared?

Answer 3

on earth divide wieght by gravitational acc.
8N/9.8m/s^2 =.82kg
20N=0.82kg*a
a=24.5m/s^2 (direct in calculator)
