Calculating distance per 1-sec interval for plot graph d vs t

AI Thread Summary
The discussion focuses on calculating the time and distance for a car accelerating from an initial velocity of 14 m/s to 24 m/s at a constant acceleration of 2.0 m/s². The time to reach 24 m/s is determined to be 5 seconds, using the formula t = (v - v0) / a. The total distance covered during this acceleration is calculated as 95 meters, using the equation d = v0(t) + 1/2(at²). There is uncertainty about computing distance at 1-second intervals, with a suggestion that the distance per second would average to 19 m, leading to a proposed distance-time graph. The discussion highlights the need for careful application of equations when considering constant acceleration.

2 travelining in a straight line initial velocity is 14m/s, at a constant acceleration of 2.0m/s^2 to a velocity of 24 m/s

a) how much time to reach velocity of 24m/s

t= v-v0/a or 24-14/2= 5 seconds

b) distance covered by car in this process?

d=v0(t) + 1/2(at^2) or (14)(5)+1/2(2)(5^2)= 70m+25m= 95m

c) compute values of the distance traveled at 1-sec intercals and carefully draw a graph of distance plotted against time for this motion?
c is the only one throwing me off

the problem doesn't say it is constant but this is the approach I took to form a graph plot

so then distance per second would be 19 m?
by taking distance/time 95m/5s
so at each second interval it would be like this t graph?

t-0 d-0
t-1 d-19
t-2 d- 38

so on and so forth?
I mean it doesn't say its constant acceleration so idk if what I did was right for c

On a), I don't think you used the equation correctly. Start with the equation for velocity and carefully apply your numbers...

v(t) = v_0 + at
 
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...
