Homework Statement Hello I'm trying to figure out how to integrate with the use of partial fractions but I'm a bit stuck on something that should probably be simple.. but I can't see it clearly How do you split up x2-8/x+3 and make it equal to (x-3) + 1/x+3 or for instance x2 +1/x-1 split up...

sorry for the confusion i included a picture link for the problm

hmm. well when I move around the equation i get k=2[0.5(mv22)/x2 from the assumption that K1 + U1 = K2 + U2 Am i going in the right direction??

euhh... I'm still a little confused..how do i find k if I don't know x?

Homework Statement In the figure, a stunt car driver negotiates the frictionless track shown in such a way that the car is barely on the track at the top of the loop. The radius of the track is 9.9 m and the mass of the car is 1800 kg. Find the force of the car on the track when the car is at...

Homework Statement A 0.80-kg block is held in place against the spring by a 67-N horizontal external force. The external force is removed, and the block is projected with a velocity v1 = 1.2 m/s upon separation from the spring. The block descends a ramp and has a velocity v2 = 1.9 m/s at the...

First of all thanks for the help! Okay so for the angle.. i redid my math and have come up with 1.92 degress after I divided by 2.5 and took the tangent inverse in -0.05= +(2.5tanα) - 4.9/36 As for the Y-offset I took the trig approach to the question and came up with 13.38 cm after I solved...

Sorry for the confusion I fixed some errors in my solution now. I think I have the right answer but am not so sure about the y offset especially..
