A net force of 40 N south acts as an object with a mass of 20kg. What is the object's acceleration

Answers

Answer:

a = 2 m/s²

Explanation:

Given: 20 g, 40N

To find: Acceleration (a)

Solution: To find the acceleration (A), divide the force by the weight

A = F ÷ m

= 40 ÷ 20

= 2 m/s²

Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.
