Unformatted text preview: 4. A block of mass 75 g is attached to a solid support by a spring. This mass is free to
move on a frictionless horizontal surface. The motion is constrained to one
dimension (along the x axis). At equilibrium the mass rests at the origin. A force of
15 N is applied to the block which compresses the spring until the mass is at x = - 8.0cm. The force is then removed. Calculate the following quantities: The spring constant, k. The velocity, v at x = 0, + 4.0, and + 8.00m. The acceleration, a at x = 0, + 4.0 and + 8.00m.
