A block m1 with mass 7 kg moves up an inclined plane with an initial velocity v=4.7 m/s. The inclined plane is at an angle of theta = 45 degrees from the horizontal. The coeff. of kinetic friction between the block and the incline is 0.25. What is the block's velocity when it has traveled a...

Sorry I got back to you so late but thank you so much. I was able to figure it out :) My answer turned out to be 0.266 m, which was the correct answer.

Hi! Thank you for helping me. :) This is what I tried to do: W = 1/2kx^2 K = 1/2mv^2 1/2kx^2 = 1/2(m+M)v^2 x^2 = [(m+M)v^2]/k x = sqrt{[(m+M)v^2]/k} x = sqrt{[(0.5+8.0)12^2]/60} x = 4.5166 m

A ball of clay of mass m = 0.5 kg strikes a block of mass M = 8.0 kg which slides on a frictionless table as it compresses a spring with spring constant k = 60 N/m. The initial speed of the ball of clay is v = 12 m/s. The spring is initially at its relaxed length. W= delta K = 1/2mv^2 W...
