Question

An object of mass 5 kg is accelerated upward at 0.5 m/s^2. What force is required?​

Answer 1

Answer:

Explanation:

Newton's second law of motion: F = ma

Force = mass times acceleration

Acceleration is the change in velocity during an interval of time:

A= ∆V/∆t = (m/s)/s = m/s^2

However, you have your acceleration as m/s, which is a velocity. I'll assume it's just an errant typo…

Force = 5kg x 2 m/s^2 = 10 kg•m/s^2 = 10 N

10 N is Ten Newton's

Newton came up with the original formula for force, so the unit of force is named after him, much like Ohm, Volt, Watt, Pascal, Hertz, Farad, etc. are named for the great scientists & engineers whom were their pioneers and/or originators.
