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?

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.

Problem 1) A car starts from rest at x 0 and 0, travelling in a straight line. The car speeds up and then slows down until it comes back to rest at a distance of 0.900 km from where it started. For the first quarter of the distance, its acceleration is +2.25 m/s2, while for the last three quarters of the distance its acceleration is -0.750 m/s2. (a) Find the travel time for the entire trip. (b) Find the maximum...
