A body of mass is dropped from above a horizontal platform that is fixed to one end of an elastic spring, as shown in the figure above. As a result the spring is compressed by an amount of What is the spring constant of the spring?
The gravitational acceleration is and the air resistance is negligible.
A body initially at rest is dropped from a height of If the coefficient of restitution is what is the height the body reaches at the second bounce?
The gravitational acceleration is
A -meter-long rod of mass with homogeneous density is standing vertically with one end on a horizontal floor. Find the gravitational potential energy of the rod.
The gravitational acceleration is
A body of mass is moving on a frictionless horizontal plane with a velocity of The body is heading to the vertical platform fixed to one end of an elastic spring, as shown in figure above. As a result the spring is compressed by an amount of What is the spring constant of the spring?
A block of mass is moving on a frictionless horizontal surface with a velocity of towards another block of mass that is moving on the same surface with a velocity of in the same direction. A massless spring of spring constant is attached to as shown in figure above. When block collides with the spring, what is the maximum change in the spring's length?
