Find critical points
Find local maxima & minima
Homework Equations
None
The Attempt at a Solution
F'(x) = x(x+2)/(x+1)^2
crit points: -2,0,-1
f(-2) = -4
f(0) = 0
f(-1)=undef
My book is telling me that f(0) is the minima, and f(-2) is the...
Well, I used the first equation, and I am receiving a negative number.
Why is it that when I solved for h, it was a number greater than the maximum height, L?
I'm very sorry, I had never taken physics before this course.
Homework Statement
The Attempt at a Solution
I used conservation of momentum for the initial velocity of mass 2, and conservation of mechanical energy for the movement from rest to highest position, KE=PE.
The answer that I received is selected in the screenshot. However, when the...
Homework Statement
A student standing on a stationary skateboard tosses a textbook, mt = 1.05 kg, to a friend standing in front of him. The student and the skateboard have a combined mass of mc = 104 kg and the book leaves his hand at a velocity of 2.25 m/s at and angle of 22 degrees with...
Homework Statement
A block with mass, m1 = 5.5 kg rests on the surface of a horizontal table which has a coefficient of static friction of μs = 0.52. This block is connected to another block by a pulley system and it hangs vertically under the influence of gravity, g. The hanging block has...
Homework Statement
A block is resting on a wooden plank. On one end of the plank is a hinge so the other end my be lifted to create and angle θ with respect to the horizontal. The plank has a coefficient of static friction of μs.
Using the sum of forces along the plank. Find the angle at which...
