A pendulum is made up of a metal cylinder of diameter d attached to a thin string. The pendulum passes through a photogate at the lowest point in its motion, as shown in the side view. The photogate measures the time t it takes the cylinder to pass through the photogate. Using this information, the mechanical energy of the system is obtained at its lowest position. The speed of the pendulum is calculated as dt. If the motion of the pendulum does not oscillate perpendicular to the photogate, as shown in the top view, how will this affect calculated total mechanical energy?.

How are momentum and impulse related? impulse is a whim to do something, while momentum keeps it going impulse is another name fore instantaneous momentum the impulse acting on and object is equal to the change of momentum it causes. the impulse that acts on and object is the momentum that results.

The force will determine the acceleration.

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
