A horizontal force of 100 N is applied to a 50.0 kg box; the box slides on a level floor and is opposed by frictional force of 20 N. Show the algebraic steps
a) What is the acceleration of the box?
b) How long does it take to move 5.0 meters?
c) What is its speed at this point (5.0 meters)?
This solution is provided in 31 words. It uses three different equations to calculate acceleration, time, and velocity.
