Net force is required to bring the truck to a stop

AI Thread Summary
To bring a 1.2 x 10^4 kg truck traveling at 22 m/s to a stop over 330 m, the required net force can be calculated using the formula Fnet = ma, where 'a' is the necessary deceleration. The initial kinetic energy of the truck must be considered, as it relates to the work done to stop the vehicle. The change in energy concept, particularly work-energy principles, is essential in determining the net force. Understanding these principles will help solve for the required force and its cause. The discussion emphasizes the importance of applying physics concepts to solve real-world problems.

Homework Statement


A 1.2*10power of 4 kg truck is traveling South as 22m/s
A)what net force is required to bring the truck to a stop in 330m
B)what is the cause of this net force

Homework Equations


Fnet=ma



The Attempt at a Solution


m=1.2*10power of 4 kg
Fnet=ma
= 1.2*10power of 4 kg

Thats as far as i got

Hint: try considering work and energy.
 
you know the trucks initial energy, right? What concept refers to change in energy?
 

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'

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...
