Apenny dropped into a wishing well reaches the bottom in 1.50 seconds. what was the velocity at impact?

.

Explanation:

The kinematic equation for velocity with constant acceleration at time t is :

.

Assuming that the initial velocity is zero

and knowing that the gravitational acceleration is

The equation is

.

After 1.5 seconds, this gives us

.

.

And this is the velocity at impact.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

he kicked it 10 feet straight up into the air? i think this works.
