A car accelerates from rest for 8.0 s, and reaches a speed of 66 m/s. How far will the car travel?
a) 8448 m
b) 2112 m
c) 264 m
d) 528 m

C

Explanation:

Find the acceleration using this kinematic equation:

Now use this kinematic equation to find the displacement:

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
