Q1. A 59.0 kg pole vaulter running at 9.5 m/s vaults over the bar. If the vaulter's horizontal component of velocity over the bar is 1.5 m/s and air resistance is disregarded, how high was the jump?

Q2. In a charging process, 5 × 10^13 electrons are removed from one metal sphere and placed on a second sphere. Then the electrical potential energy associated with the two spheres is found to be -0.072 J. firstly, both metal spheres are neutral.

The value of the Coulomb constant is 8.98555 × 109 N • m2/C2 and the charge on an electron is 1.6 × 10-19 C.

What is distance between the two spheres?
