Answer:

[See Below]

Explanation:

✦ Formula = Mass / 1000

  ✧ 4800 / 1000 = 4.8

So 4800 grams is equal to 4.8 kilograms.

Vesna [10]

Answers:

A) 0.204 m

B) 0.285 s

Explanation:

<h2>Answer A:</h2>

This described situation is free fall, this means the initial velocity of the fly is zero, and the equation that will be used is:

y=y_{o}+V_{o}t-\frac{1}{2}gt^{2} (1)

Where:

y is the final height of the fly

y_{o}=40 cm=0.4 m is the initial height of the fly

V_{o}=0 is the initial velocity of the fly

t=200(10)^{-3} s is the time

g=9.8 m/s^{2} is the acceleration due to gravity

y=0.4 m+0-\frac{1}{2}(9.8 m/s^{2})(200(10)^{-3} s)^{2} (2)

y=0.204 m (3)  This is the distance at which the fly would begin to beat its wings

<h2>Answer B:</h2>

In this part we will also use equation (1), but we will find the time:

y=y_{o}+V_{o}t-\frac{1}{2}gt^{2} (1)

Where:

y=0 is the final height of the fly

y_{o}=40 cm=0.4 m is the initial height of the fly

V_{o}=0 is the initial velocity of the fly

t is the time  we need to find

g=9.8 m/s^{2} is the acceleration due to gravity

0=0.4 m+0-\frac{1}{2}(9.8 m/s^{2})t^{2} (4)

Isolating t:

t^{2}=\frac{(-2)(-0.4 m)}{9.8 m/s^{2}} (5)

t=0.285 s (6)  This is the time it would take for a fly to hit the bottom of the box
