Q. In a dental X-ray machine a bean of electrons is accelerated by a potential difference of 10 kV. At the end of the acceleration, how much kinetic energy does each electron have if they start from rest?

Q. Blocks of mass m_1 and m_2 are connected by a massless string that passes over the pulley. The pulley turns on frictionless bearings, and mass m_1 slides on a horizontal, frictionless surface. Mass m_2 is released while the blocks are at rest.Suppose the pulley has mass m_p and radius R. Find the acceleration of m_1.
