When an object falls freely, the formula for the distance it falls is d= 4.9t^2 where d is

german

Answer:

a) 122.5 m ; b) 10 s

Step-by-step explanation:

Just use the given equation and plug in what you know.

d = 4.9t^2

d = 4.9(5^2)

d = 4.9 * 25

d = 122.5 m

d = 4.9t^2

490 = 4.9t^2

100 = t^2

t = 10 s

A snail moves at the speed of 76 millimeters per minute. Nancy writes the following steps to calculate this speed in centimeters

gizmo_the_mogwai [7]

Answer:

The step 3 is incorrect in the conversion, is not necessary

Step-by-step explanation:

we have

The speed is $76\frac{mm}{min}$

we know that

1 mm=0.1 cm

1 min=1/60 h

$76\frac{mm}{min}=76(0.1)/(1/60)=76(0.1)(60)=456\frac{cm}{h}$

step 1

Multiply 76 by 0.1

$76(0.1)=7.6$

The step 1 is correct

step 2

Multiply the result obtained in step 1 by 60.

$7.6(60)=456$

The step 2 is correct

step 3

Multiply the result obtained in step 2 by 60

<u><em>This step is not correct</em></u>

therefore

The step 3 is incorrect in the conversion, is not necessary
