Given information
Given:
A car is accelerating from 55 km/h to 70 km/h as it rounds a curve of constant radius.
To Determine:
For each of the cases, sketch and label the total acceleration vector, the radial acceleration vector, and the tangential acceleration vector
Step-by-step explanation
A car is accelerating from 
to
on a circular track will have radial as well tangential accelerations. When a car rounds a curve of constant radius, then the radial acceleration 
and the tangential acceleration 
are perpendicular to each other.
The fact that the car is speeding up means that the tangential acceleration
is in the same direction as the car's velocity
. The normal (centripetal) acceleration
points in the direction of the curve's center. The total acceleration is a vector sum of these two
