Yuki888 [10]

Answer:

0.2 m

Explanation:

PHASE 1

First, we calculate the distance the tongue moved in the first 20 ms (0.02 secs). We use one of Newton's equations of linear motion:

s = ut + \frac{1}{2}at^2

where u = initial velocity = 0 m/s

a = acceleration = 250 m/s^2

t = time = 0.02 s

Therefore:

s = 0 + \frac{1}{2} * 250 * (0.02)^2\\\\\\s = 0.05 m

PHASE 2

Then, for the next 30 ms (0.03 secs), we use the formula:

distance = speed * time

This speed is the same as the final velocity of the tongue after the first 20 ms.

This can be obtained by using the formula:

v = u + at\\\\=> v = 0 + (250 * 0.02)\\\\\\v = 5 m/s

Therefore:

distance = 5 * 0.03 = 0.15 m

Therefore, the total distance moved by the tongue in the 50 ms interval is:

0.05 + 0.15 = 0.2 m
