The correct answer is the Soccer ball is 3.2 plus 5 that’s your answer.
When the elevator is going up (assuming the elevator is acceleration)
When the elevator is accelerating downwards, the total gravitational force would be larger.
If the elevator is accelerating upwards, then the gravitation force would be smaller, thus the tension in the string would be smaller.
Answer:
The answer is D. The electrons will flow from an area of high potential energy to an area of low potential energy.
X== low potential energy
Y = high potential energy
z = flow of electrons
Explanation:
1. V = Vo + a*t.
<span>15 = 0 + a*5 a = 3 m/s^2. </span>
<span>2. V = Vo + a*t. </span>
<span>0 = 15 - 5*t, t = 3 s. </span>
<span>3. d1 = Vo*t + 0.5a*t^2. </span>
<span>Vo = 0, t = 5, a = 3 m/s^2, d1 = ?. </span>
<span>d2 = Vo*t. Vo = 15 m/s, t = 15 s, </span>
<span>d2 = ?. </span>
<span>V^2 = Vo^2 + 2a*d3. </span>
<span>V = 0, Vo = 15 m/s, a = -5 m/s^2, d3 = ?. </span>
<span>d1+d2+d3 = Total dist.</span>
