The car in the figure speeds up as it turns around the quarter-circle curve. When exactly halfway around the curve, the car's acceleration is a = 2.0 m/s^2 at an angle of 15° below the horizontal. (a) What is the value of at, the component of the acceleration that is tangent to the circle? (b) What is the value of ar, the component of the acceleration that is perpendicular to the circle? This component is also known as the radial acceleration.

Step 1

The car is moving around a quarter-circle curve and is halfway around the curve. The total acceleration \( \mathbf{a} \) of the car is given as \( 2.0 \, \text{m/s}^2 \) at an angle of \( 15^\circ \) below the horizontal. Show more…
