College Physics Problem 2.16

A cheetah can accelerate from rest to a speed of 30.0 m/s in 7.00 s. What is its acceleration?

SOLUTION:

The formula for acceleration is 

a=\frac{change\:in\:velocity}{time}=\frac{\Delta v}{time}=\frac{v_f-v_0}{t}

Substituting the given values

a=\frac{30.0\:\frac{m}{s}-0}{7.00\:s}

a=4.29\:m/s^{2}
