Part A and B did not ask for radial acceleration. A) what are the angular speed and angular acceleration of the car at this instant? B) What is the total linear acceleration of the car? C) If the angular acceleration remains constant, what will the radial acceleration be after 1.4s? Unless I...

I guess I have a hard question? Im thinking to solve this is by using the constant formulas. I really am confused on this tho.

How do I find the radial acceleration after 1.4 seconds if the angular acceleration remains constant?

Homework Statement A car is going around a corner with a radius of 68m. At one instant, its speed is 19m/s and its speed is increasing at a rate of 3.2m/s^2. What are the angular speed and the angular acceleration of the car at this instant? What is the total linear acceleration of the car...

Homework Statement What is the magnitude of the Impulse exerted on a 920-kg car as it slows from 24.3 m/s to 12.9 m/s while traveling in a straight line? The Attempt at a Solution I was thinking 920(24.3 m/s) and 920(12.9 m/s) and subtract the two. Not totally sure tho.

Homework Statement What has to be true in order for the momentum of a system to be conserved? Homework Equations The Attempt at a Solution I am thinking the net force needs to be zero. Just wanting to confirm this is correct. Thanks in advance
