Question

If the frog lands with a velocity equal to its average velocity and comes to a full stop 0.25s later, what is the frog’s average acceleration?

Answer 1

Answer:

Average accelation = -4V

Explanation:

$a=\frac{V-V0}{t}$

V=0 m/s (because the frog stopped)

V0 = V (average velocity)

t= 0,25 s

So;

$a=\frac{V-V0}{t}=\frac{0-V}{0.25}=-4V$
