A student working on a school project modeled a trampoline as a spring obeying Hookes law and measured the spring constant of a certain trampoline as 4617 N/m. If a child of mass 27.0 kg compresses the trampoline vertically by a maximum of 0.25 m, while bouncing up and down, what is the childs acceleration at the moment of maximum compression?
A block of mass ? = 0.25 kg is connected to a vertically oriented spring with a force constant of ? = 50 N/m by a massless string that passes over a massless and frictionless pulley, as shown in the figure. The system is at equilibrium. If released from rest, how much does the block descend before it comes to rest momentarily?
A block of mass ?=3.80 kg slides along a horizontal table with velocity ?0=1.50 m/s. At ?=0, it hits a spring with spring constant ?=41.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by ?=0.400. How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.
