Question

a force of 1.35 newtons is required to accelerate a book by 1.5 meters/second2 along a frictionless surface. what is the mass of the bo

Answer 1

Hi there!

Recall Newton's Second Law:

$\large\boxed{\Sigma F = ma}}$

∑F = Net force (N)

m = mass (kg)

a = acceleration (m/s²)

Rearrange the equation to solve for mass.

Working equation:

$\large\boxed{m = \frac{F}{a}}$

Plug in the given values:

$\frac{1.35}{1.5} = \boxed{.9 kg}$
