ok so for Fx:
I set it up as T = (mg)sin25
cos 31
My answer was: 5508.2 N
For Fy: N = (mg)cos25 - Tsin31
I plugged T into that equation and my answer was: 7288.3 N
Is that correct? What's my next step?
A 1140 kg car is held in place by a light cable on a very smooth (frictionless) ramp, as shown in the figure. The cable makes an angle of 31.0 degrees above the surface of the ramp, and the ramp itself rises at 25.0 degrees above the horizontal.
Find the tension in the cable. (T=?)
How...
I used c^2 =a^2 + b^2 - 2abcostheta to solve for the resultant. How would I solve for the components? I was trying to before and I couldn't seem to get the correct answer.
The two blocks in the figure (Intro 1 figure) are connected by a heavy uniform rope with a mass of 4.00 kg . An upward force of 200N is applied as shown.
(See attachment)
I figured out the acceleration to be 3.53m/s^2
The tension at the top of the heavy rope is 120N.
How would I find...
"I'd do it the way you've done it. If I draw it I get the exact same expressions for the x- and y-components as you do."
It's not giving me the correct answer.
Two dogs pull horizontally on ropes attached to a post; the angle between the ropes is 59.0 degrees. Dog A exerts a force of 254 N and dog B exerts a force of 328 N.
Find the magnitude of the resultant force.
Find the angle the resultant force makes with dog A's rope.
I'm having...
I figured out how to solve for the height above the ground and got 15.9m which is correct.
Now I need How fast is it moving just before it hits the building?
Firemen are shooting a stream of water at a burning building using a high-pressure hose that shoots out the water with a speed of 25.0 {\rm m/s} as it leaves the end of the hose. Once it leaves the hose, the water moves in projectile motion. The firemen adjust the angle of elevation \alpha of...
Thank you for your help everyone. I'm still having trouble with it though.
I need to Find the direction of the bird's acceleration and also Find the angle between the bird's velocity vector and the horizontal.
I tried using Vinitial = Vsin(t)
I plugged in 8 =(3)Sin(5)
I took the arc...
