Answer:
- a.

- b.

Explanation:
<h3>
a.</h3>
The equation for the voltage V of discharging capacitor in an RC circuit at time t is:

where
is the initial voltage, and
is the time constant.
For our problem, we know

and

So





This gives us

and this is the time constant.
<h3>
b.</h3>
At t = 18.8 s we got:



Answer:
The force is calculated as 338.66 N
Explanation:
We know that force is given by

We know that range of a projectile is given by

it is given that R=130 m applying values in the above equation we get

Thus the force is obtained as

Thus force equals
