AI Thread Summary
To calculate the average velocity of a remote-controlled vehicle that starts at 1.0 m/s forward and accelerates at 0.08 m/s² backward for 4.0 seconds, the relevant equation is Vavg = deltaD/deltaT. The initial speed and acceleration provide enough information to determine the total distance traveled during the 4 seconds. The key steps involve calculating the change in distance (deltaD) using the initial speed and the effects of acceleration over the given time. The discussion emphasizes understanding the relationship between speed, acceleration, and time to solve the problem effectively. Proper application of kinematic equations will yield the average velocity.

Homework Statement



Calculate the average velocity for a remote controlled vehicle that starts with a speed of 1.0 m/s [forward] and then accelerates at 0.08 m/s2 [backward] for 4.0 s


Homework Equations



Vavg=deltaD/deltaT

The Attempt at a Solution



I'm unsure of how to go about this even though it seems its an easy question. Is there enough information to even solve it? Wouldn't i need the time at which it travels forward? Thanks for any help

Hi adhoward24! :smile:

(have a delta: ∆ and try using the X2 tag just above the Reply box :wink:)

I don't understand this …

you know its speed at t = 0, and you know ∆t = 4.

Hint: find an equation for ∆D, and divide it by ∆t. :wink:
 

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...
