4) The tires of a certain car begin to lose their grip on the pavement at an acceleration of 5 m/s2.
If the car has this acceleration, how many seconds does it require to reach a speed of 25 m/s
starting from 10 m/s?

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
