Pretty simple distance traveled given acceleration problem

AI Thread Summary
To calculate the distance a bicyclist must travel to reach a speed of 7.8 m/s with an acceleration of 1.0 m/s², the kinematic equation can be applied. The relevant formula is d = (v² - u²) / (2a), where v is the final velocity, u is the initial velocity (0 in this case), and a is the acceleration. By substituting the values into the equation, the correct distance can be determined. The discussion emphasizes the importance of using the right kinematic equations for solving physics problems. Understanding these principles is crucial for accurately answering homework questions.

Homework Statement


Hey, I am not sure why I can't get the right answer for my online physics homework, it keeps telling me the answer I am putting is wrong! My question is:

The light turns green, and a bicyclist starts forward with an acceleration of 1.0 m/s^2. How far must she travel to reach a speed of 7.8 m/s?

I think I am going about figuring it out the wrong way...

Thanks for any help! :)

Awesome thank you...ill see what i come up with
 

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'

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...
