2 Your answer is partially correct. Try again. In the figure, a slab of mass m, = 40 kg rests on a frictionless floor, and a block of mass m, = 9 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force F of magnitude 102 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab? u = 0- (a) Number T-7.4 -7.4 Units m/s^2 (b) Number i+ Units m/s^2 -0.88 Click if you would like to Show Work for this question: Open Show Work SHOW HINT LINK TO TEXT LINK TO SAMPLE PROBLEM LINK TO SAMPLE PROBLEM VIDEO MINI-LECTURE 10:50 PM search ENG 4/4/2021 ond 111Pgup) pri sc DOUSE insert dele home break 13) 23 bac 3 5. 4 R.
