tudy A lab student fires a 0.5 kg projectile with speed 10 m/s into a ballistic pendulum with a mass of 1.5 kg attached to a massless string 1.0 m in length. What angle does the string makes with the vertical if the pendulum rises to a height after impact?

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.
