A8.75-kg block is sent up a ramp inclined at an angle θ = 30.5° from the horizontal. it is given an initial velocity v0 = 15.0 m/s up the ramp. between the block and the ramp, the coefficient of kinetic friction is μk = 0.353 and the coefficient of static friction is μs = 0.639. how far up the ramp (in the direction along the ramp) does the block go before it comes to a stop?

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1

Juan created a chart to him study for a test. which headings best complete the chart? x: transparent objects y: opaque objects x: opaque objects y: transparent objects x: high frequency waves y: low frequency waves x: low frequency waves y: high frequency waves

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,?
