AI Thread Summary
The discussion revolves around calculating the final velocity of a rocket sled driven by Sara, which starts from rest and accelerates up a 15-degree ramp. The acceleration is given as 8 m/s², and the problem simplifies the angle's impact during the sled's motion up the ramp. The relevant formula to determine the final velocity is V² = 2*a*x, where 'a' is acceleration and 'x' is the distance traveled. However, the angle will become significant once the sled leaves the ramp and enters projectile motion. Understanding these components is crucial for solving the problem accurately.

HI guys, I am having a lot of trouble with determining initial velocity, x and y components etc. Can someone please help me with this

Sara drives a rocket sled from rest 25 m up a 15 degree ramp at an acceleration of 8 m/s2. Whats the final velocity?

Thank you

Thank you

The way the problem is worded means that the angle is of no concern because the m*g*Sin15 term is absorbed by the statement that it accelerates at 8m/s2 up the ramp.

This suggests that you are only concerned with V2 = 2*a*x

Of course the angle is of concern with regard to what happens after it leaves the ramp.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
