Answer :
There are two cases in this problem :
1). When the ion is positively charged :
Now, the ion and the substance both are positively charged hence when brought together will repel each other because equal charged particles repel each other.
2). When the ion is negatively charged
Now, the substance is positively charged and the ion is negatively charged so both will attract each other because the particles with opposite charges attract each other.
Answer: 32 and 34 is the answer
The distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds
<u>Explanation:</u>
Given:
Height, h = 75 foot
Initial velocity, u = 107 foot/sec
Equation:
h = -16t² + 107t + 75
Substituting the equation:
75 = -16t² + 107t + 75
0 = -16t² + 107t
16t² = 107t
t = 6.6875s
We know:
Distance = speed X time
d = 107 f/s X 6.6875s
d = 715.56 foot
Therefore, the distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds
