May you professors please check part b of my work because my answer does not match the answer in the back of the book. Thank you.
Question:
(a) What is the total random kinetic energy of all the molecules
in 1 mol of hydrogen at a temperature of 300 K? (b) With what
speed would a mole of...
so according to your equation, i should get the following equation:
KEf = (.5)(.250)(15.0^2) + (.250)(9.8)(2pi.6) + (30.0)(1.2)
Im not sure what change of x is.
Thank you very much for helping.
Hi I just need confirmation on a problem.
Q: A softball pitcher rotates a 0.250-kg ball around a vertical circular path of radius 0.600 m before releasing it. The pitcher exerts a 30.0-N force directed parallel to the motion of the ball around the complete circular path. The speed of the...
Question:
The driver of a truck slams on the brakes when he sees a tree blocking the road. The truck slows down uniformly with an acceleration of -5.60 m/s2 for 4.20 s, making skid marks 62.4 m long that end at the tree. With what speed does the truck then strike the tree?
