Question

What calculation will give us the sum of the force that acts on the object, in newtons (which are km•m/s²)?

a) F = m•a
b) F = 2m•a
c) F = m/2•a
d) F = 2•m/a

Answer 1

The sum of the force on an object is calculated using the formula F = m·a, where F is force in newtons, m is mass in kilograms, and a is acceleration in meters per second squared. For a 55 kg wagon accelerating at 0.0255 m/s², the force would be 1.4025 N.

Step-by-step explanation:

The calculation that will give us the sum of the force that acts on the object, in newtons (which are km·m/s²), is a) F = m·a, according to Newton's second law of motion. For example, if a wagon with a mass of 55 kg accelerates at a rate of 0.0255 m/s², the force on the wagon can be calculated using the formula F = m·a. Inserting the values, we get F = (55 kg) × (0.0255 m/s²) = 1.4025 N, which is the force in newtons.
