AI Thread Summary
To find the acceleration due to gravity on a planet with no atmosphere, the kinematic equation D = v0t + 1/2 * g * t^2 is applicable. Given that the object falls 2.66 meters in the first second from rest, the initial velocity (v0) is zero. By substituting the known values into the equation, the acceleration (g) can be calculated. This approach effectively utilizes the provided time, initial velocity, and distance to solve for gravitational acceleration. The final result will be expressed in units of m/s^2.

An object is released from rest on a planet that has no atmosphere. The object falls freely for 2.66m in the first second. What is the magnitude of the acceleration due to gravity on the planet? Answer in units of m/s^2

What kinematic equation would I use for this?

D=v0t + 1/2 *g*t2 might be a good place to start.

You have time, initial velocity, and distance. So solve for acceleration (g)
 

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...
