Newton's second law says force (f) is equal to mass (m) times acceration (a). A scientist wants to calculate the force of an object where the acceleration of gravity (g) is 9.8 m/s2. Use the function to calculate the force for an object with a mass (m) of 0.29 kilograms.

Answers

Force = mass x accerelation
= 0.29 x 9.8
= 2.842 N

Answer:

2.842 N


Step-by-step explanation:

Newton's second law is given by the equation  F=ma

Where,

  • F is the force in Newtons
  • m is the mass in kilograms (kg)
  • a is acceleration given in meters per second squared

Given in the problem,

m = 0.29 kg, and

a = 9.8 meters per second squared


Substituting into the formula gives us F:

F=ma\nF=(0.29)(9.8)\nF=2.842  Newtons (N)
