These are the questions I don't get, I did all my other exam review. It's high school physics, like really easy stuff, so you will probably think this is stupid.(adsbygoogle = window.adsbygoogle || []).push({});

4) A ball is thrown at an angle of 20 degrees at 20 m/s. How high did it go? What is the horizontal distance?

5) An object is shot horizontally from a roof 100m high at a velocity of 5m/s. How far from the base will the object strike the ground.

7) A 10kg box is pulled 20 degrees with a force of 40N at a constant speed. What is the coefficient of friction?

8) A 10kg box is resting on a 40 degree incline. What is the Normal and Parallel force on the box?

2. Relevant equations

a=(vf-vo)/t

d/t=.5(vf+vi)

3. The attempt at a solution

4) I don't know how to set this up. I know how to do the trig work once I get the maximum height, I can't think of how to get there though.

5) Once again, I don't even know how to set this up. I don't think our teacher ever even taught us this. Whats the base the object will strike at mean?

7) Is the force expression Fnet = Fh - Ff? If so how do you get both of them

8) Is this Fparallel = 63.014? If so, what is Fn?
