Ok I think I’ve got it… is this right?
TO FIND a:
S = 3m, t= 3.05sec
s = ut + ½ at2
3 = 0*3.05 + ½ * a*(3.05)2
3 = ½ * a* 9.303
0.322 = a / 2
2*0.322 = a
a = 0.644m/s2
TO FIND Ff:
Mass = 50g
a = (g*sin theta) - F/m
0.644 = (9.8*sin9) -...
ok I'm stuck again...
Í was looking over in a textbook and the 'F' in the equation doesn't stand for frictional force, but the net force. Is that the same as friction? I'm so confused...
And i have no way of measuring 'a' so there are two unknowns in the equation and i cannot solve it...
No wait... if i use that equation, won't it be the same for each ball..?
can i use [s = ut + 1/2 at^2] for inclined planes, or is that just for flat surfaces?
oh... thanks!
so if i use an inclined plane i can place the ball at the same spot each time, and release without using any force...
is: [a = g x sin theta] the right equation to use to find acceleration?
but then how would i find the friction?
Hi. I am doing an experiment on golf balls. I know that the dimples are supposed to reduce the resistance when traveling through the air. I am testing the effects that dimples have on rolling resistance when on the ground.
I am using 3 golf balls of the same type/brand.
One, I am keeping it...
