Homework Statement Picture link http://i1120.photobucket.com/albums/l498/LaLadude/2.jpg How long does it take to reach the ground? And what is the angle of impact with the ground? Homework Equations The Attempt at a Solution Δy = Voy * t + (1/2)ay * t2 t = (-5 m/s) ± √(5 m/s)2...

draw the triangle on the inside of the picture? I am so losttt :cry:

I noticed I'm missing a negative in the y direction, but how will I correctly break it into its components? I can make a triangle from the dotted line to the bottom arrow of C, but I'm not so sure of what to use.

Thanks.. Would it just be 20m * cos80° in the y-direction and none in the x-dir?

Homework Statement Compute the magnitude of the displacement (\vec{}R and the angle with respect to the x-axis. Homework Equations The Attempt at a Solution A = 10m * sin30° \hat{}y+ 10m * cos30° \hat{}x \vec{}A = 5m \hat{}y + 8.66m \hat{}x B = 15m C = 20m * sin80°...

I added a picture link if it'll help.

Oh, okay! Thank you so much :biggrin:

LOL Yes, I did mean that. So it will be \mu_{}s = Ff / N? Which will be 69.3N/79.3N..correct?

Homework Statement Suppose a block of mass = 10kg is on an incline plane that makes an angle = 45° from the horizontal. If a force of 10 N is being applied to the block, downward, and perpendicular to the surface, and the block is not moving, what is the static force of friction? What is the...

I'm still not understanding it. :confused:

okay, so for T1 and T2.. x-dir would be ∑Fx = - T1 cos30 + T2 cos10 = 0 y-dir would be ∑Fy = T1 cos30 + T2 cos10 + -mg = 0 Then solve for T1 = T2 cos10/cos30 = 0 Plug into y-dir eq. (T2 cos10/cos30) cos30 + T2 cos10 = mg T2 = mg/1.97 which is 4.97. Then plug T2 to T1. Correct...

Homework Statement If a ball is being twirled in a circle with a radius of 0.5m, and then is let go such that the balls velocity makes an angle 30 degrees from the horizontal and then covers a distance of 1,000m before it hits the ground. What was the centripetal accelertaion provided by the...

Homework Statement Given this diagram and the masses involved, what is the Tension in each string. All masses are 1kg. Diagram provided Sorry, the angle for T2 is 10° Homework Equations The Attempt at a Solution I really don't know where to start.
