Calculate the Change in Velocity of a Van

AI Thread Summary
To calculate the change in velocity of a van, one must consider both the initial and final velocity vectors. The van initially travels north at 28 m/s and then turns to head 40 degrees east of north at 25 m/s. The change in velocity is determined by finding the vector that, when added to the initial velocity, results in the final velocity. Participants are reminded to show their prior calculations to adhere to forum guidelines. Proper vector addition is essential for an accurate solution.

can anyone help me:


a van is traveling north at a speed of 28ms-1. after turning a corner its heading is 40 degrees east of north at 25ms-1. workout the change in velocity of the van

Welcome to PF michael,

Could you please post what you have attempted thus far.

The change in the velocity is the velocity vector that when it is added to the initial velocity one would get the final velocity. That is the initial velocity vector plus the change in the velocity vector gives one the final velocity vector.

andrevdh,

Please do not provide help to posters who do not show any prior working, it is both contrary to the forum guidelines and the ethos of the Science Education forums.

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'
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...
