For the following problem, show all work. Circle your answers. A box of mass m = 5.0 kg is sitting on a ramp, which is elevated at an angle 0 = 20°, compressing a spring Ar = 0.5 m. The spring is released, causing the box to slide up the ramp. At some point, the spring becomes detached from the box. The total length of the ramp is L = 4.0 m and it has a coefficient of kinetic friction...

1.) AT the top of a 30 m hill is a 5kg mass. It is loaded into a spring cannon. The cannon's spring has a constant k=400 N/m and the spring is compressed 40cm. The mass is initially at rest. Therefore there is no friction. (A.) What was the stored energy in the spring before it was released? (B.) What was the gravitational potential energy of the mass with respect to the bottom of the hill? (C.) What was the...

A box of mass m=12.0 kg is located at the top of a ramp of height h=8.00 m, as shown in the figure. The coefficient of kinetic friction between the ramp and the box is μk=0.5. You give the box a push so that it starts sliding down with an initial speed of 3.00 m/s. The box continues its motion on a rough horizontal surface for 5.00 m until it hits a spring of spring constant k=150. N/m and fully compresses it by 50.0 cm and comes to rest. What is...

top of the loop.
After the block slides down the loop from point C to D, it
enters the rough portion of the track. The speed of the block at
point D is the same as point B, and the speed of the block at point
E is half the speed of the block at point D.
