Question

A car speeds up in a circular path. Which of the following figures illustrates the acceleration of the car?

Moderate

Solution

Net acceleration: a = $\sqrt{{a_{c}}^{2} + {a_{t}}^{2}}$
= $\sqrt{{(\frac{v^{2}}{R})}^{2} + {a_{t}}^{2}}$
As v increases, a also increases.
So size of arrow should be increasing and angle between velocity and acceleration should be acute.
