In the figure, a slab of mass m1 = 40 kg rests on a frictionless floor, and a block of mass m2 = 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 of magnitude 103 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?

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.
