The mass m = 5.5 kg resting on a frictionless horizontal table is connected to a horizontal spring with stiffness constant k = 200 N/m . The mass is pulled a distance to the right so that the spring is stretched a distance x0 = 1.9 m initially, and then the mass is released from rest.

B: Determine the kinetic energy when x=1/2 x0

C: Determine the maximum kinetic energy.

D: Determine the maximum speed.

E: At what position it occurs?

F: Determine the maximum acceleration.

G: At what position it occurs?

A block of mass 9.1 kg rests on a horizontal frictionless floor, and is connected to a vertical wall by a spring of force constant 205 N/mN/m as shown in the figure. When the spring is in its equilibrium position (neither stretched nor compressed), the block just touches a second lighter block of mass 3.4 kg at rest on the frictionless floor. The spring is now compressed by 0.12 mm (only the heavier mass is moved towards the wall) and...
