Abartender slides a beer mug at 1.7 m/s towards a customer at the end of a frictionless bar that is 1.0 m tall. the customer makes a grab for the mug and misses, and the mug sails off the end of the bar. (a) how far away from the end of the bar does the mug hit the floor? m (b) what are the speed and direction of the mug at impact?

Explanation:

Given

velocity of mug with which it leaves the bar is 1.7 m/s

Also

height of bar=1 m

Considering motion in vertical direction

here

t=0.451 s

so horizontal distance traveled is

here a=0

speed of mug will be combination of horizontal and vertical velocity

thus

for direction

is with x axis in clockwise sense

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq
