The solution is 0.2798m. How is it possible? working backwards I found the acceleration to be around 21m/s^2. Isn't the acceleration suppose to be less than gravity? Can someone help me point out where i went wrong please? (please refer to my calculations above for my steps on finding the...

Thanks for the tip, but i don't quite get your formula for acceleration. Can you explain more? For the potential energy, yeah, i forgot about that. After revising my calculations, i still got the wrong answer. Kinetic energy of block = 0.5mv^2 -0.5mu^2 (where v = final velocity and u =...

Homework Statement Find the amount which the spring is compressed after the mass comes to rest. Assume a kinetic coefficient of friction of 0.11 and an initial velocity along the surface of v = 4m/s. Given values : mass = 2.2kg k = 500 N/m delta = 0.036m theta = 23 degrees The...
