Question

A solid cylinder of mass 5 kg and radius of 0.1m is released from on a ramp and rolls without slipping. If height of the ramp is 3 m what is the most nearly the linear velocity of the cylinder when it reaches the bottom of the ramp? 39 m/s 7.7 m/s 6.3 m/s 5.4 m/s none * not sure of the signs for b,c,d* A cylinder whose mass moment of inertia 1= 12 kg.m2 is rotating at angular velocity of 500 RPM. A constant moment of m= -120N m is applied for 10 seconds what is the most nearly the final angular velocity of the cylinder? -455 -50 400 380 e- none 10-A block of mass 100 kg is sliding across a rough, flat surface with coefficient of friction Mu= 0.6 between the block and the surface; what is most nearly the amount of work done to overcome friction to slide the block a distance of 20 meters across this surface. 1.2 KJ 2 KJ 11.8KJ 19.6KJ
