Q. A slab of mass m1 = 4.3 kg rests on a frictionless floor, and a block of mass m2 = 1.3 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force of magnitude 100 N begins to pull directly on the block. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab?
Describe the displacement of the airplane when the radar was tracking it-RBA=RB-RA. What are the components of RBA.
A 282 kg log is pulled up a ramp by means of the rope that is parallel to the surface of the ramp. The ramp is inclined at 23.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.87, and the log has..
W hat are underwater angles of refraction
The kinetic friction force between surface and disk slows down its linear motion while at the same time making the disk spin on its axis at an accelerating rate. Finally, the disk's rotation catches up with its linear motion, and disk begins to roll ..
Assume you are 80cm from a plane mirror. What area of the mirror is used to reflect rays entering one eye from a point on the tip of your nose if your pupil diameter is 5.60 mm.
For instance, the flute can be described as an open-open pipe because a flutist covers the mouthpiece of flute only partially. Meanwhile, a clarinet can be described as an open-closed pipe as the mouthpiece of the clarinet is almost completely closed..

Long, long ago, on a planet far, far away, a physics experiment was carried out. First, a 0.250- ball with zero net charge was dropped from rest at a height of 1.70. The ball landed 0.400 later. Next, the ball was given a net charge of 7.85 and dropp..
A particular organ pipe can resonate at 231 Hz, 385 Hz, and 539 Hz, but not at any other frequencies in between. Is it an open or a closed pipe? What is the fundamental frequency of this pipe.
