A2.0 kg wood block is launched up a wooden ramp that is inclined at a 27 ∘ angle. the block's initial speed is 13 m/s . the coefficient of kinetic friction of wood on wood is μk=0.200. you may want to review (page 131) . for with math skills, you may want to review: vector components part a what vertical height does the block reach above its starting point? express your answer to two significant figures and include the appropriate units. view available hint(s) hh = nothing nothing part b what speed does it have when it slides back down to its starting point? express your answer to two significant figures and include the appropriate units. view available hint(s) vv = nothing nothing provide feedback

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
