A student uses a weight hanger and string to apply 0.001 newton weights to a cup in the horizontal direction. if the cup is 3 newtons and takes 3 weights to cause motion what is the coefficient of static friction?
-0.001
-0.009
-0.03
-0.1
-0.3
Homework Answers
Concept: here we use the Newton's law of motion
and static friction to find out the solution, The applied force
will be equal to the static friction when it causes the object to
move,

VU22475 Apply Scientific Principles to Engineering Problems Calculate the maximum deceleration of a car that is heading down a 8 slope (one that makes an angle of 8 with the horizontal). You may assume that the weight of the car is evenly distributed on all four tires and that the coefficient of static friction is involved - that is, the tires are not allowed to slip during the deceleration. The...

Calculating the Coefficient of Static Friction (Pinewood on painted steal) From Empirical Data Background: **An object at rest remains at rest unless a force is applied to it." This paraphrases a portion of Newton's First law of motion. In the case of this lab a minimum amount of force must be applied to overcome the attraction between two surfaces. The amount of force needed to start the motion...

A civil engineer wishes to redesign the curved roadway in the figure in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when the road is covered with ice. Such a ramp is usually banked, which means that the roadway is tilted toward the inside of the curve. Suppose the designated speed for the road...

(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...

5) (10 pts) John is baby-sitting Casey, his 3-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As John starts across the street, he exerts a 58 N forward force on the wagon. There is a 20 N resistance force (friction) and the wagon and Casey have a combined weight of 302 N. Construct a free body diagram showing all the forces acting upon...
