The acceleration of the car is
Explanation:
The acceleration of an object is given by
where
v is the final velocity
u is the initial velocity
t is the time elapsed
Here we have to convert the initial and final velocity of the vehicle into SI units. So we have:
is the initial velocity
is the final velocity
t = 5 s is the time elapsed
Solving for a, we find the acceleration:

Answer:
The internal resistance of the cell is 0.051 ohm.
Explanation:
Given;
emf of the battery, E = 12 V
terminal voltage of the cell, V = 8.2 V
current in the circuit, I = 75 A
let the potential drop of the cell due to internal resistance (r) = Ir
The internal resistance of the cell is calculated from the equation below;
E = V + Ir
where;
r is the internal resistance of the cell
Therefore, the internal resistance of the cell is 0.051 ohm.
