(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In a local bar, a customer slides an empty beer mug down the counter for a refill. The bartender is momentarily distrated and does not see the mug, which slikde off the counter and strikes the floor 1.40m from the base of the counter. If the height of the counter is 0.860m

a)With what velocity did the mug leave the counter?

b0What was the direction of the mug's velocity just before it hit the floor?

2. Relevant equations

my x-component is 1.40m and y-component is 0.86m

My initial equation would be vyf=vyi + ayt

which turns into (?) 0=visintheta(i)/g

3. The attempt at a solution

I have no idea on how to start computing for this problem. I have no angle for sine, and wouldnt my acceleration be -9.80m/s^2, being that we're dealing with height here????

Thanks so much in advance!!
