A race car starts from rest on a circular track. The car increases its speed at a constant rate a; as it goes once around the track. Find the angle that the total acceleration of the car makes- with the radius connecting the center of the track and the car- at the moment the car completes the circle.

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.
A car on a straight level road, starts from rest and accelerates to a speed of 1,846 ft/'s in 49 seconds. What is the car's average acceleration in ft/s??
Car A was traveling east at high speed when it collided at point with car B, which was traveling north at 46 mi/h. Car C, which was traveling west at 61 mi/h, was 32 ft east and 10 ft north of point at the time of the collision. Because the pavement was wet, the driver of car C could not prevent his car from sliding into the other two cars, and the three cars, stuck together, kept sliding until they...
A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.550 m/s2. (a) What is the magnitude of its net linear acceleration 19.0 s later? (b) What angle does this net acceleration vector make with the car's velocity at this time? Question 6 A car starts from rest and moves around a circular track of radius 32.0 m. Its speed increases at the constant rate of 0.550...
