AI Thread Summary
To calculate the velocity of a stunt car driven on a flat train car relative to Earth, you would add the speed of the stunt car to the speed of the train if both are moving in the same direction. This approach is similar to walking on a moving sidewalk, where your speed is combined with the sidewalk's speed. If the stunt car is moving toward the train's engine, the direction of the velocities must be considered. Understanding relative motion is crucial in physics, especially in velocity calculations. This concept is essential for solving similar problems in the future.

A stunt car is driven along a flat train car. The stunt car is moving toward the engine of the train. How would you calculate the velocity of the stunt car relative to earth?

Im in physics 11 and we are almost done our velocity chapter and this question was on our review.

Why not just add the car speed to the train speed if they are in the same direction (like walking on a moving sidewalk)?
 
ooh okay thanks, makes sense
 

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...
