Answer to Question #126081 in Molecular Physics | Thermodynamics for Albert

Question

a 54 newton horizontal force pushes a 5.0 kg mass sitting on a horizontal surface. Additionally , the horizontal surface exerts a 30 newton frictional force on the mass. What is the acceleration of the mass?

Answer 1

Solution:

F_(total) = F_(applied) - F_(friction)

F_(total) = 54 - 30 = 24N

F_(total) = 24N

acceleration:

F_(total) = ma

$a = \tfrac{F(total)}{m}$

$a = 4.8 [ \tfrac{m}{s^2}]$
