A small block is placed on a rotating 45 degree funnel at a distance of 5 cm from the axis of rotation. The coefficient of friction of the block on the funnel surface is 0.5. Determine the minimum and maximum rotating rpms of the funnel such that the block does not slide up or down the funnel, but remains in the same fixed spot with respect to the funnel.

An object slides down an inclined plane of angle 20° and of incline length 3 m. If the initial speed of the object is 3 m/s directed down the incline, what is the speed at the bottom? Neglect friction.

Starting from rest, the elevator ascends, attaining its maximum speed of 1.24 m/s in 1.50 s. It travels with this constant speed for the next 5.00 s. The elevator then undergoes a uniform acceleration in the negative y direction for 1.80 s and comes to rest.
a) What does the spring scale register before the elevator starts to move?

(b) What does it register during the first 1.50 s?

(c) What does it register while the elevator is traveling at constant speed?

(d) What does it register during the time it is slowing down?

A force F is applied to the object at 40.0° to the horizontal, pushing it upward on the plane. The coefficients of static and kinetic friction between the block and the plane are, respectively, 0.342 and 0.156.
(a) What is the minimum value of F that will prevent the block from slipping down the plane?

(b) What is the minimum value of F that will start the block moving up the plane?

(c) What value of F will move the block up the plane with constant velocity?

sry, im a total dumbass &can't figure this out.

delta d = (v1 +v2) / 2 x delta t.
im trying to solve for v1. help?

The universe will eventualy die due to expansion right??? if thats true then is this theory possible???
The Eternal Return is basically the theory that there is infinite time and a finite number of events, and eventually the events will recur again and again infinitely. Consider the world as a super-complex chess game. If games of chess are played one after another forever, eventually a game will be repeated since there is only a finite number of possible games, it is the same with the world; eventually events will recur in the same order. The world is an eternal process of coming to be and passing away. The process, however, has no beginning or end. Eventually every combination of matter and energy will be realized and repeated and infinite number of times. it was one of the main topics of the philosopher nietzsche.

(this is NOT reincarnation, it is reliving life over and over EXACTLY down to the last detail. its the same life over and over for all eternity)


the thought is very disturbing cause we have to relive this life over and over forever. and i have NOT had an easy life

i always thought it was known fact that the universe has been expanding since it came into existence and eventualy particles with expand and break apart and eventualy the universe will cease to exist. this is fact right? i even learned this in school.

I understand how it becomes less dense through the heating process, but why does less density = rising? Does it have to do with the surrounding air being more dense and the two interacting like a bubble in water? Does it have to do with gravity? What's the deal?

In Figure P18.50, suppose that the switch has been closed for a length of time sufficiently long enough for the capacitor to become fully charged. (R = 12.0 k, R2 = 19.0 k, R3 = 3.00 k, V = 9.10 V)

Figure P18.50

(a) Find the steady-state current in each resistor. IR = µA
IR2 = µA
IR3 = µA

(b) Find the charge on the capacitor.
µC
