AI Thread Summary
To solve the vector problem, the initial velocity is 8.0 m/s at 25 degrees, and the final velocity is 11.0 m/s at 140 degrees over a time of 4.0 seconds. The acceleration can be calculated using the equation V2 = V1 + a*t, where the velocities need to be converted into vector components. The displacement can be found using the average velocity during the time interval. Clear guidance on breaking down the vectors and applying the equations of motion is needed to find both acceleration and displacement accurately. Understanding vector addition and the kinematic equations is crucial for solving this problem effectively.

Homework Statement


If a car has an initial velocity of 8.0m/s, 25degrees and turns in 4.0 s so it ends up traveling at 11.0m/s, 140degrees find:
a)the acceleration
b)the displacement for the 4.0 s

Have a go at it and then come back.
 
ok I will try but I hardly know where to start
 
a)

V1-8.0m/s, -25degrees
V2-11.0m/s,-140degrees
acceleration-
displacement-
time-4.0s

eq.V2=V1+a*t
11.0m/s,-140degrees=8.0m/s, -25degrees+a*4.0s

now I am not sure if this is how you would start this can someone steer me in the right direction?
 

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. 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'

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...
