Question

A 4.0-kilogram object is accelerated at 3.0 meters

Answer 1

Answer;

  = 6.0 m/s²

Explanation and solution

• According to Newton's second Law of motion the resultant force is directly proportional to the rate of change in momentum.

• Therefore; F = ma , where F is the force, m is the mass and a is the acceleration

F = 4 × 3

  = 12 Newtons

The same force acts on a 2.0 kg object

F = ma

a = F/ m

  = 12 /2

  = 6.0 m/s²

Answer 2

6.0 m/s^2
12 N= 2 kg (a)
a=6 m/s^2
