Answer:
1)X(t)=Xo±Vo(t)±*a
2)a(t)=
Explanation:
1)with this formula you can determine the position of the object studied when you have an accelerated, or deaccelerated motion, where Xo its your beginning position, and Vo is your beginning speed, and t is the difference of time between the final time and the initial time. The signs of the equation (+ or -) depends if its displacement its increasing on time, or diminishing, it means : positive speed, and acceleration, and in the oposite case negative speed and acceleration respectively.
2)this formula lets you know the variation of speed at each time (considering its constant), so if you have a constant variation of speed along a determined time, then you can use it.
This formula is used in uniformly accelerated rectilinear motion

ANSWER
R = 3 Ω
EXPLANATION
This is a circuit made of a power source and a resistor. To find the resistance on the resistor, we have to use Ohm's Law,
If we plot the measures in a current-voltage graph, the slope of that graph is the inverse of the resistance,
The slope of the line of best fit is approximately 1/3, which means that the resistance is 3 Ω.
If we apply Ohm's Law to get the resistance for each pair of measures (V, I), we should obtain a value around 3:
• For (6, 2):
• For (8, 2.7):
• For (10, 3.3):
• For (12, 4):
• For (14, 4.7):
Hence, the resistance is 3 Ω.
