What is the magnitude of the car’s acceleration on a circular bend?

AI Thread Summary
The discussion focuses on calculating the magnitude of a car's acceleration while it travels counterclockwise on a circular bend with a radius of 180 m and a speed of 26 m/s, while decelerating at 1.0 m/s². Participants clarify that the formula v²/r calculates centripetal acceleration, but the car's overall acceleration also includes tangential acceleration due to its deceleration. The need to understand both types of acceleration is emphasized, as they combine to determine the total acceleration. The conversation highlights the importance of distinguishing between centripetal and tangential acceleration in circular motion problems. Understanding these concepts is crucial for accurately solving the problem presented.

A car is traveling counterclockwise along a circular bend in the road with an effective radius of 180 m. At a certain instant, the car’s speed is 26 m/s, but it is slowing down at a rate of 1.0 m/s2. What is the magnitude of the car’s acceleration?

I thought it was v^2/r but that isn't the answer apparently.

that's the centripetal acceleration

what about the tangential acceleration?​
 
I don't even know what that is or how to go about finding that.
 
I still don't know how to do it. But thanks for your help

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 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...
