Q. At time t=0 a grinding wheel has an angular velocity of 26.0 rad/s. It has a constant angular acceleration of 29.0 rad/s^2 until a circuit breaker trips at time t = 2.50 s. From then on, the wheel turns during an angle of 440 rad as it coasts to a stop at constant angular deceleration.
Through what total angle did wheel turn between and the time it stopped? At what time does the wheel stop? What was the wheel's angular acceleration as it slowed down?
A wooden raft has a mass of 45 kg. When empty it floats in water (density 1000 kg/m3) with 68% of its volume submerged. What mass of sand could be put on the raft without it sinking.
A 210, 50-cm-diameter turntable rotates on frictionless bearings at 67. A 25 block sits at the center of the turntable. A compressed spring shoots the block thoroughly outward next to a frictionless groove in the surface of turntable.
A 1500 kg car traveling at a speed of 20 m/s skids to a halt on wet concrete where kinetic friction= 0.20. How far are the skid marks.
Huygens' principle (first described by the Dutch scientist Christiaan Huygens in 1678) uses geometry to determine the shape of a wavefront at a time.
The mass of a roller-coaster car, including its passengers, is 495kg. Its speed at the bottom of the track in the figure below is 17.00 m/s. The radius of this section of track is r1 = 26 m. Find the force that a seat in the roller-coaster car exerts..
What is the final angular velocity
A 0.65kg block of ice is sliding by you on a very slippery floor at 3 m/s. As it goes by, you give it a kick vertical to its path. Your foot is in contact with the ice block for 0.003 seconds.
What is wave number
What is the childs total mechanical energy. If the speed of the child at the lowest position is 2.00 m/s, what is the change in mechanical energy due to friction.
