I know I need to find Vf for the speed when the mug hits the floor. And then direction idk

I don't know how to solve the problem with the equations I do have though...

[b]1. A bartender slides a beer mug at 1.50m/s towards a customer at the end of a frictionless bar that is 1.2m tall. the customer makes a grab for the mug and misses, and the mug sails of the end of the bar. What are the speed and direction of the mug at impact? [b]2. Vx=Vocosθ Vy=Vosinθ...

okay...no clue where to even begin

How do I get to the homework forum? I thought I was in it already haha

Hmm..how does this relate to the angles? Like where is the 90° coming from?

Okay this is EXACTLY where I am getting stuck! Could you work this out for me?

Okay...sorry but you completely lost me again? Any way you could dumb this down?

If you could tell me how to combine the horizontal and vertical componenets with an angle involved, it would be so helpful for me to try the problem

I don't know what the horizonatl and vertical components of velocity are...can you help please! Vertical acceleration is 9.8m/s^2 (I think) No horizontal acceleration A=Vf-Vi/Tf-Ti?? Then where does the 30° come in?

[b]1. a projectile is fired into the air at a projection angle of 30° above the ground. its initial speed is 327 m/s. what is its speed 3 seconds later [b]2. vf^2=Vi^2+2AΔX [b]3. So, the angle is 30, Vi=327m/s, Tf=3. trying to find Vf...I'm guessing combine horizontal and...

A freshman and you're taking AP Physics? Wow, I'm a junior. How would Newtons Fnet equation help to find Vi?

Right, that's where I'm getting stuck is trying to find Vi. Do you have any good website suggestions that are helpful for trying to understand this a bit better?

Can you explain a little more on that?

Maybe 180°? Why does that matter? If a problem gave you an angle that was over the limit, what happens?
