What is the current in a circuit with a 6.0 v battery and a 2.0 ω resistor?

For this case, we have by definition, that Ohm's Law states that:

Where:

I: It's the current

V: It's the voltage

R: It's the resistance

We have to:

R = 2Ω

Substituting:

Also, we have that the units of the current, by dividing volts between ohms, will be amps.

Thus, the current is

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
