An automobile is moving at speed of 2.00 m/s along a circular road of radius 20 m.
A) Find the time it takes to make one full circle when the car is still moving at constant speed. (1P)
B) Find the car radial acceleration during this time. (1P) Then its speed starts increasing at a rate of 0.600 m/s2 while it stays on the same road.
C)How long would it take for the car to make one full turn from the moment it started its tangential acceleration?

A car is going along a circular road at a constant speed. The radius of the curve is 290 m, and the car takes 1.7 minutes to complete one round. Calculate its centripetal acceleration in m/s2.
(9.2.70) A car drives around a circular track of radius 50 m. The car starts at rest at time t = 0, and its speed increases at a rate of 3.00 m/s. (a) Draw a top view illustrating the motion of the car around the circle, and also a side view showing a free-body diagram for the car (b) Find an equation which gives the magnitude of the net acceleration vector as a function of time (incorporating both radial and...
At time t = 0 s, automobile A is traveling at a speed of 17.5 m/s along a straight road and is picking up speed with an acceleration that has a magnitude of 4.00 m/s2 as in part a of the figure. At t = 0 s, automobile B is traveling at a speed of 17.5 m/s in uniform circular motion as it negotiates a turn (part b of the figure). It has a centripetal acceleration whose magnitude is also...
A race car starts from rest on a circular track of radius 400 m. Its speed increases at the constant rate of 0.500 m/s. At the point where the magnitudes of the radial and tangential accelerations are equal, determine (a) the speed of the race car, and (b) the elapsed time.

Suppose you are driving a car in a counterclockwise direction on a circular road whose radius is r 28 m/s (about 63 mi/h) 385 m (see the figure). You look at the speedometer and it reads a steady T(decreasing) (a) Constant angular speed (b) Decreasing angular speed Concepts (i) Does an object traveling at a constant tangential speed (for example, vT= 28 m/s) along a circular path have an acceleration? Yes No (ii) Is there a tangential acceleration aT when...
This figure (|a| = 14.5 m/s2) represents the total acceleration of a particle moving clockwise in a circle of radius r = 1.70 m at a certain instant of time. (a) For that instant, find the radial acceleration of the particle. m/s2 (toward the center) (b) For that instant, find the speed of the particle. m/s (c) For that instant, find its tangential acceleration. m/s2 (in the direction of the motion)
A racing car travels with a constant tangential speed of 75.0 m/s around a circular track of radius 625 m. Find |(a) The magnitude of the car's total acceleration and |(b) The direction of its total acceleration relative to the radial direction.
car moving along a straight section of road starts from rest, accelerating at 2.00 m/s? until it reaches a speed of 25.0 m/s. Then the vehicle moves for 87.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s (a) How long is the three-wheeled car in motion (in s)? (b) What is the average velocity of the three-wheeled car for the motion described? (Enter the magnitude in m/s.)...
