Question1
A bolt drops from the ceiling of a train car that is accelerating northward at a rate of 3.50 m/s2.
(a) What is acceleration of the bolt relative to train car?
(b) What is acceleration of the bolt relative to Earth?
Question2
A 200, 45.0-cm-diameter turntable rotates on frictionless bearings at 63.0 rpm. A 19.0g block sits at the center of a turntable. A compressed spring shoots the block radically outward along a frictionless groove in the surface of a turntable.
Question3
A 199-kg log is pulled up a ramp by means of a rope that is parallel to the surface of ramp. The ramp is inclined at 32.5 ° with respect to the horizontal. The coefficient of kinetic friction between log and ramp is 0.872, and the log has an acceleration of 0.724 m/s2. Find out the tension in the rope.
