1. You have a mass hanging off of a frictionless pulley (massless string). The other mass is on a table. The weight of the mass causes the block on the table to slide at an acceleration. There is friction between the block and the table. What would the coefficient of kinetic friction be for this...
I just lost 20 points on my last physics test because of making stupid careless mistakes
how can i cut down on these
my teacher doesn't give partial credit
on one question i thought it asked to find the maximum height, it turned out that it asked for the Range the object traveled...
If i were to use a square shaped aluminum foil. What would be the best design for a penny barge. I was thinking a boatshaped one, but i realized its hard to fold a boat without retangular paper
Thanks what I'm confused with
i assumed you multiply that solution by 4
however, i looked up the formula for the area of an oval
It's the length of the major axis/2 x length of the minor axis/2 x pi
therefore the answer would be 2.5pi
that is equal to when i evaluated it from 0 to...
Find the area under the parametric curve (clearly a circle):
x=5sin(t)
y=2cos(t)
domain of t: [0,2pi]
h(t)=x
g(t)=y
integral from alpha to beta (lower to upper) of g(t)h'(t)dt
integral from 0 to pi/2 of 10cos(t)^2
10(x/2+sin2x/4) evaluated from 0 to pi/2
solution: 2.5pi...
how would u implement kinetic friction and springs into a momentum question?
None of the questions in my textbook shows a momentum+friction/springs question
lets say
Car A (350 kg) is traveling 60 m/s east and car B (400 kg) is traveling 30 m/s west. The collision is completely elastic...
Homework Statement
A bullet of mass m is shot into a block of mass M that rests on a rough surface with coefficient of kinetic friction k. The block slides for a distance of x meters before coming to a stop. Derive an expression for the initial velocity of the bullet.
