Answer:

1. A 1 kg object accelerated at a constant 5 m/s2. Estimate the net force needed to accelerate the object.

Known :

Mass (m) = 1 kg

Acceleration (a) = 5 m/s2

Wanted : net force (∑F)

Solution :

We use Newton’s second law to get the net force.

∑F = m a

∑F = (1 kg)(5 m/s2) = 5 kg m/s2 = 5 Newton

Newton's second law of motion – problems and solutions 1

Known :

Mass (m) = 1 kg

Net force (∑F) = 2 Newton

Wanted : The magnitude and direction of the acceleration (a)

Solution :

a = ∑F / m

a = 2 / 1

a = 2 m/s2

The direction of the acceleration = the direction of the net force (∑F)
