A
79 at time t=0, a rock
climber accidentally allows a
piton to fall freely from a high
point on the rock wall to the val-
ley below him. then, after a
short delay, his climbing partner,
who is 10 m higher on the wall,
throws a piton downward. the
positions y of the pitons versus t
during the falling are given in
fig. 2-40. with what speed is the
second piton thrown?

Well the magnitude of its acceleration related to that car starts with the oil change like when you have to change the oil in your car you have to make sure that your precious car is starting really propley and very well

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
