How Do Two Knights Collide When Accelerating Towards Each Other?

AI Thread Summary
Two knights, Sir George and Sir Alfred, start 88.0 meters apart and accelerate towards each other with different rates: 0.300 m/s² and 0.200 m/s², respectively. The discussion involves calculating the point of collision relative to Sir George's starting position using kinematic equations. The key formula for displacement in terms of time and acceleration is highlighted, leading to the conclusion that the knights will collide at a specific distance from Sir George's starting point. The calculations focus on determining the time of collision based on their accelerations. Ultimately, the problem is resolved through the application of these kinematic principles.

1. two knights on horseback start from rest 88.0 m apart and ride directly toward each other to do battle. Sir George's acceleation has a magnitude of 0.300 m/s^2, Sir Alfred's has a magnitude of 0.200 m/s^2. Relative to Sir George's starting point, where do the knights collide?



2. a= (v-v0)/(t-t0), v=(x-x0)/(t-t0)



3. 0.300m/s^2=(v-0)/t, v=0.300m/s^2*t, 0.300m/s^2*t=(x-x0)/t, I don't know where to go from here!

You have a formula for displacement in terms of time and acceleration... try to use that to get the time when they collide...
 
x=(0.300m/s^2 *t^2)/2 ?
 
nevermind, I got it now!
 
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...

Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
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...
