Homework Statement
Find the Taylor series for 0.5x^2[e^x-e^(-x)] around x=0. What is the coefficient of x^n?
Homework Equations
e^x=∑x^n/n!
The Attempt at a Solution
I understand how to find the Taylor series for this equation (it being ∑[x^(2n+3)/n!]; x^3+x^5+x^7/2!+...) through...
Friction?
So on the flat surface you find the force of friction?
FFk=μk*FN
FFk=0.50*20N
FFk=10N
How would you find the applied force using this though?
With this doesn't the formula a=F(net)/m still leave two variables?
Figure out the new acceleration of the box, once it starts sliding on the flat ground.
How would you find this? Would you use a=F(net)m? If yes, how would you find the applied force?
Homework Statement
A 2kg box is at the top of an inclined plane that is 10m long. The inclined plane makes an angle of 30° with the ground. The μk of the ramp is 0.36 and the μk of the flat ground at the end of the ramp is 0.50. How far does the box travel along the flat ground until it stops...
