A value for friction isn't introduced until "C". Therefore it is assumed as friction-less prior to this.
I know "A" is correct. It is easy enough. However, the solution I was given for "B" is Favg = (0+7.07+*100)/2 = 353.3N
This confuses me . I thought the equation should be Favg = ½mv2 But...
Homework Statement
A 2kg box traveling at a velocity of 5 m/s hits a spring (k=100 N/cm). Find
a. How much the spring will compress
b. What is the average force on the spring
c. If the surface has μs = 0.15 and μk = 0.12, how far will the box rebound from the spring
d. If the surface is...
Ok, well basically...
I'm trying to determine what spring to use to ensure the tarp remains tight, even during snow fall.
There are three arches supporting the tarp and all four ends are attached to springs. The north/south ends (20' length side) are attached in an arch shape and the east/west...
Homework Statement
The distance from the spring attachment to the arch in 9 feet.
The distance from the arch to the arch is 20 feet.
There are three arches. So, End plate-spring to arch to arch to arch to spring-end plate.
The tarp weights 750 lbs and is 60 ft by 20 ft.
There are 20 springs...
