AI Thread Summary
To determine the average deceleration of a car traveling at 13 m/s that comes to rest over a distance of 640 m, the final velocity is 0 m/s. The discussion emphasizes using the appropriate equations of motion to solve the problem. Participants encourage sharing previous attempts to facilitate better assistance. The average deceleration can be calculated to be approximately 0.1 m/s². Engaging with the community and following forum rules is also highlighted for effective learning.

I am stuck on this homework question can i have some help please?

A car is traveling at 13ms-1. It is allowed to slow down naturally without applying the brakes. The distance traveled in coming to rest is 640m.

Show that the average deceleration of the car is about 0.1ms-2.

What have you tried thus far?
 
Welcome to the board! :)

Ok, here's a little help, since it comes to rest, the final velocity should be 0m/s. Now you have initial velocity, final velocity & displacement, try applying the suitable equation of motion.

But as Hootenanny said, you need to show us your attempts before asking for any help. Take care of that and have a look at the rules. :smile:
 
Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Thread 'A cylinder connected to a hanged 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...
