Question

please explain me every step please .. will rate high for goodexplanations of steps thank you
In a local bar, a customer slides an empty beer mug down thecounter for a refill. The bartender is momentarily distracted anddoes not see the mug, which slides off the counter and strikes thefloor 1.60 m from the base of the counter.The height of the counter is 0.710m. (a) With what velocity did the mug leave thecounter?___________m/s
(b) What was the direction of the mug's velocity just before it hitthe floor?____° (below the horizontal)

(b) What was the direction of the mug's velocity just before it hitthe floor?____° (below the horizontal)

Explanation / Answer

let the mug leave the counter with v m/s initial vertical velocity=0 vertical acceleration=g=9.8 h=0.71 t=time taken to hit the floor from the edge of the counter h=u*t+(1/2)*g*t2 0.71=0+(1/2)*9.8*t2t=0.38 s initial horizontal velocity=v m/s horizontal acceleration=0 horizontal displacement=1.6 m 1.6=v*0.38 v=4.21 m/s (ans) vertical velocity just before hitting the floor=V V=u+g*t V=0+9.8*0.38 V=3.724 m/s direction of the mug just before hitting thefloor=tan-1(3.724/4.21)=41.49 degree(below thehorizontal)
