3 0/2 points Previous Answers PSE6 4.P.011 My Notes In a local bar, a customer slides an empty beer mug down the counter for a refill. The bartender is momentarily distracted and does not see the mug, which slides off the counter and strikes the floor 0.40 m from the base of the counter. The height of the counter is 0.820 m. (a) With what velocity did the mug leave the counter? 4.01 Your response differs from the correct answer by more than 100%, m/s (b) What was the direction of the mugs velocity just before it hit the floor? 80.1202 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.

Answer #1


Let theInitial horizontal vel coity ofthe mug is (%) In horizontal motion velocity is uniform,there is no acceleration (a,-0) Let t is the time taken by the mug to reach the ground 2(0.82m) 9.8m/s 0.409 s Velocity of the mug to leave the counter is, 0.40m 0.409s =0.9778m/s 0.98m/s (b) Direction of mugs velocity before hits the ground is tan θ= 그 = tan (9.8m/s2)0.409s 0.9778m/s = tan- =762ダ 76.3
