Finding Acceleration Given Coordinates

AI Thread Summary
To find the acceleration of an object moving with uniform acceleration, the initial velocity is 11.0 cm/s, and the displacement over 2.75 seconds is from 2.91 cm to -5.00 cm, totaling a displacement of -7.91 cm. The relevant SUVAT equation relates initial velocity, displacement, time, and acceleration. By substituting the known values into the equation, the acceleration can be calculated. The result is an acceleration of -10.1 cm/s², indicating the object is decelerating in the negative x-direction. Understanding the SUVAT equations is crucial for solving problems involving constant acceleration.

No idea how to do this.

An object moving with uniform acceleration has a velocity of 11.0 cm/s in the positive x-direction when its x-coordinate is 2.91 cm. If its x-coordinate 2.75 s later is −5.00 cm, what is its acceleration?

The answer is -10.1 cm/s squared but I don't know how to get to the answer. Any help would be great. Thanks.

As you know velocity=Δdisplacement/Δtime.
What do you know about constant acceleration definition?
 
Perhaps look at one of the SUVAT equation of motion.

You know the displacement s, the time t and the initial velocity v.

I'll let you decide which equation you need to solve for "a".
 

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...
