A block of weight W can slide on a horizontal surface. A force of W/n1 is applied to the right that causes the block to accelerate with acceleration equal to g/n2. g is the acceleration by reason of gravity. If the coefficient of kinetic friction is ..
An astronaut travels to an alternate universe that contains infinite charged plane and no other charged objects. The astronaut observes that the electric field in this universe has a magnitude of 1.20 N/C everywhere and points directly away from the ..
What is the speed of bulky cart after the collision
Phonology: All the data for this problem come from a conservative dialect of Vèneto, a Romance language spoken in northern Italy near the city of Padua.
According to the Guinness Book of World Records (1990 edition, p. 169), the highest rotary speed ever attained was 2010 m/s (4500 mph). The rotating rod was 15 cm (5.9 in) long. Imagine the speed quoted is that of the end of the rod.
What is magnitude of the net force on the student
What is the breaking strength
A rifle with a barrel length of 56 fires an 8 bullet with a horizontal speed of 350. The bullet strikes a block of wood and penetrates to a depth of 14. (a) What resistive force (assumed to be constant) does the wood exert on the bullet? (b) How long..
Two non conservative forces are present: friction does -2.00 104 J of work on the car, and a chain mechanism does +3.00 104 J of work to help the car up a long climb. What is the transform in the car's kinetic energy, ΔKE = KEf - KE0, from A to B.
Explain the spacing between allowed vibrational energy levels
What is new angular speed of the merry-go-round
The potential at location A is 392 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 780 V, and when released from rest from this spot, the particle arrives at B wit..
