Imagine you are driving around a horizontal circular track (such as a roundabout at an intersection or freeway exit). You are driving at a constant speed of 12.0 km/h, and your circular path has a radius of 18.0 meters. (a) When you are at the northernmost point on the circular track and driving towards the west, what is your acceleration? Give your answer in m/s2. also give direction b) When you are at the westernmost point on the circular track and driving towards the south, what is your acceleration? also give the direction

You ride a bicycle around on a circular track while accelerating. The circle has a radius of 22 m and your cell phone tells you that your total acceleration is 12 m/s2 making an angle 44⁰ from the forward direction of your bike (t̂) into the circle. Find: (a) your radial acceleration, (b) your current speed, and (c) the rate of change of your speed.

You are driving to the grocery store at 25 m/s . You are 110 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.70 s and that your car brakes with constant acceleration. -How far are you from the intersection when you begin to apply the brakes? -What acceleration will bring you to rest right at the intersection? -How long does it take you to stop? A rock is tossed straight up with...
