Answer:
7.0 m/s
Step-by-step explanation:
We can solve this using the 2 kinematic equations and you can use either:
So let's use the first one.
Vi = initial velocity
Vf = final velocity
a = acceleration due to gravity (constant 9.8m/s²)
t = time
The marble is dropped so this means that it is in free fall. The initial velocity is always 0m/s.
We are given then the following:
d = 2.5m
t = 0.71s
Vi = 0 m/s
a = 9.8m/s²
So we plug in the values we know and solve:
20 < 12 ⋅ <em>x</em> = 64
This is somewhat of a false equation though, due to the left side "20" is not less than the right side "12
", which means that the given statement is false.
So I switched it up and made the variable "12"
<u>12 < 20 ⋅ </u><u><em>x</em></u><u> = 64
</u>
12x - 20 = 64
12x = 64 + 20
12x = 84
12x⁄12 = 84⁄12
x = 7
