**physics pencil torqu**

A pencil, 15.7 cm long, is released from a vertical position with the eraser end resting on a table. The eraser does not slip. Treat the pencil like a uniform rod. What is the angular speed of the pencil just before it hits the table? What is the angular speed of the pencil ...

**physics torque i think please help**

Three joggers are running along straight lines as follows: Jogger A, with a mass of 55.2kg, is traveling along the line y=6.00m at 3.45 m/s in the positive x-direction. Jogger B, with a mass of 62.4kg, is traveling at 4.23 m/s along the line x=3.00m in the positive y-direction...

A person of mass 84kg is at rest at the bottom of an inclined plane that makes an angle of 30 degrees with the horizontal. he walks up the inclined plane through a certain distance and has a speed of 0.40 m/s. How much net work has been accomplished in walking through that ...

**physics work and newton**

A 2.0 kg object starts from rest from the top of an inclined plane that makes an angle of 30 degrees with the horizontal and has a rise of .4m. It slides down the inclined plane and at the bottom has a kinetic energy of 60J. Ignore friction and use g = 10.m/s2. what is the ...

**Physics, newtons laws**

A 50kg block is being pulled up a 13 degree slope by a force directed 30 degrees above the slope.? The coeffcienct of kinetic friction between the block and the slope is 0.200. What is the minimum force required for the block to continue to slide up the plane with no ...
