Question

A spring of stiffness 101 N/m (initially unstretched) is attached to a mass 6 kg on a frictionless table. This mass is connected to another via a rope to a 2 kg dangling mass. The dangling mass is given a downward velocity of 9 m/s. Calculate the maximum extension of the spring, in m.

What stiffness is required in a spring if it is to Launch a 12 kg Mass 30 m into the air after being compressed by 0.25 m
A lab assistant has suspended a spring from a door frame. When an object is attached to the spring's bottom end, the spring extends downward by an additional distance, d, measuring 4.80 cm. (That downward distance is relative to the unstretched position that the spring had previously held when in equilibrium, as shown by the horizontal dashed line in the figure below). Calculate the mass of the hanging object (in kg) if the spring constant k has the value 59.5 N/m. 1. kg
An object has a mass of 0.5 kg is placed in front of a compressed spring. When the spring was released, the 0.5kg object collides with another object with mass 1.5kg and they move together as one unit. Find the velocity of boxes if the spring constant is 40N/m, and spring. was initially compressed by 20cm. Answer with text and/or attachments:
A mass weighting 32 lbs stretches a spring 8 inches. The mass is in a medium that exerts a viscous resistance of 38 lbs when the mass has a velocity of 4 ft/sec.
