ha ZeroPotential Datum MA mg k
The figure shown below is released from rest with the spring unstretched. Use the datum shown for zero gravitational potential energy. For the values given below answer the following questions:
Position 1 is Ha1
μk=0.14
k=32.5 Nm
hA1=0.6 m
mA=4.6 kg
mB=1.3 kg
What is the Gravitational Potential Energy for mass mA at position 1 (remember your signs)?
What is the Gravitational Potential at position 1 for mB?
What is the Potential Energy of the spring at position 1?
What is the Kinetic Energy at position 1 for mA?
What is the Kinetic Energy at position 1 for mB?
Again we have the figure shown below that was released from rest with the spring unstretched. Use the datum shown for zero gravitational potential energy. At position 2 the spring is at its max stretch. Remember we have the values below; answer the following questions:
μk=0.14
k=32.5 Nm
hA1=0.6 m
mA=4.6 kg
mB=1.3 kg
What is the max stretch in the spring?
