Question

A car negotiate a bend of radius 20m with an acceleration of 12m/s². What is the maximum speed of the car attained without skipping?

Answer 1

Solution:

$$a= \frac {v^2}{R}$$

$$v^2=aR$$

$$v= \sqrt {aR}$$

$$v= \sqrt {12\times 20}\approx19 \frac {m}{s}$$

Answer: $\approx 19 \frac {m}{s}$
