I believe that formula is incomplete, if it is derived from the kinematic equations.
The full formula being
where:
s is the displacement (or how far she travelled in your question)
u is the initial velocity, which I think can be assumed to be 0 m/s
t is the time taken which is 120 s
a is the acceleration due to gravity which points down in a negative y direction, which is -9.8 m/
Since initial velocity, u, is assumed to be 0 m/s the equation becomes:
Substitute in a = -9.8m/ and t = 120 s and calculate your answer.
Tell me what you calculate the answer to be (don't forget units) and I'll let you know if it's right.
Nitric acid (NHO3) because plants need nitrogen to survive, hope this helped.
E = I R
That means
Voltage = (current) x (resistance)
= (2.5 A) x (2.4 ohms)
= 6 volts .
