Thank you soooo, much. The problem was just that I had the velocity in the wrong units. I would have spent forever on that problem!

Homework Statement A spring (80 N/m) has an equilibrium length of 1.00 m. The spring is compressed to a length of 0.50 m and a mass of 2.2 kg is placed at its free end on a frictionless slope which makes an angle of 41 degrees with respect to the horizontal. The spring is then released...

This is another one that I have given several attempts. Calculate the thermal energy dissipated from brakes in a 1600 kg car that descends a 20 degree hill. The car begins braking when its speed is 95 km/h and slows to a speed of 30 km/h in a distance of 0.27 km measured along the road. I...

This problem has been giving me some trouble, and I was wondering if anyone could help? A 0.700 kg wood block is firmly attached to a very light horizontal spring (k = 200 N/m) as shown in the figure (Intro 1 figure) . This block-spring system, when compressed 4.7 cm and released, stretches...
