2. (4) Newton’s 2nd law is F = ma. What must be the acceleration of a 4.0 kg box being pulled along a friction-free surface if the net pulling force is 20.0 N? Show all work.
Homework Answers
Applied force = 20 N
Mass of box = 4 kg
Using Newton's second law
F = m×a
20 = 4×a
a = 20/4 = 5 m/s2
therefore the acceleration of the 4 kg box when pulled by a force of 20 N = 5 m/s 2

You are pulling a 6.8 kg box with rope with a force of 5.5 N. The rope is 35° above thehorizontal. For a while you are pulling across ice that is very smooth. Later you reach a patch of snow which has a kinetic coefficient of friction of 0.2 and a static coefficient of friction of 0.35 with the box. A)Draw the free body diagrams for the box when it is on the ice and when it is on the...

Q1. Starting with ar = v ^2 /r, show that for any object moving
in a circle with constant centripetal acceleration ar pulling
inwards, the theoretical rotation period is given by Pth = 2πr v =
2π r ar .
Q2. Does the rotation period change with increased tension in
the way you would expect from theoretical grounds? If you increase
the tension by pulling down on the hanging mass while the rubber...

A 50.0-kg crate is being pulled along a horizontal, smooth surface The pulling force is 10.0 N and is directed 20.0" above the horizontal What is the acceleration of the crate? An object of mass 25 kg, attached to an ideal massless spring, is pulled across a frictionless surface. If the spring constant is 100 N/m and the spring is stretched by 0.5 m, calculate the acceleration of the object when released.
