A6.25 kg block is sent up a ramp inclined at an angle =31.5° from the horizontal. it is given an initial velocity =15.0 m/s up the ramp. between the block and the ramp, the coefficient of kinetic friction is =0.368 and the coefficient of static friction is =0.663. how far up the ramp in the direction along the ramp does the block go before it comes to a stop?

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
