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.

Supermodified race cars, such as the one shown in the image, are
built with their massive engines mounted to the left side of the
car between the two left wheels.
What
advantage does this give the car?
The offset engine moves the race car's center of mass to the
left, making it easier to turn left.
Moving the engine has no effect on the race car. It can be
treated as a point mass.

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
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.

8). (15 points) Two train cars are on a straight, horizontal track. One car starts at rest and is put in motion with a constant acceleration of 2.50 m/s2. This car moves toward a second car that is 32.0 m away. The second car is moving away from the first car and is traveling at a constant speed of 4.50 m/s. a) Where will the cars collide? b) How long will it take for the cars to collide?
