What is the average resultant force on a truck making a 90 degree turn?

AI Thread Summary
To determine the average resultant force on a truck making a 90-degree turn, the problem involves calculating the change in velocity and the resulting acceleration. The truck's mass is 3000 kg, with an initial speed of 4.0 m/s and a final speed of 7.0 m/s over a time interval of 5.0 seconds. The change in velocity (ΔV) must consider both the magnitude and direction, as it is a vector quantity. The average resultant force can be calculated using the formula F = m * a, where acceleration (a) is derived from ΔV/Δt. Understanding the vector nature of velocity is crucial for accurately solving this centripetal force problem.

Homework Statement


a 3000 kg truck traveling at a speed of 4.0 m/s makes a 90 degree turn in a time of 5.0 s and emerges from this turn with a speed of 7.0 m/s. what is the magnitude of the average resultant force on the truck during this turn?


Homework Equations





The Attempt at a Solution


I think this might be a centripetal force problem but the change in velocities is messing me up.

What is force? F = m*a

What is acceleration? ΔV/Δt

So ... what is the ΔV ... keeping in mind that V is a vector?

You have the Δt conveniently given as 5 sec.
 

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...
