Q1. A cart of mass M = 1.2 kg can roll without friction on a level track. A light string draped over a light, frictionless pulley connects the cart to a hanger with mass m = 0.5 kg. The cart is released from rest, allowing it to roll, pulled by falling hanger.

Q2. The beryllium isotope 4Be is unstable, decays into two α particles (mα = 6.68 10-27 kg), and releases 1.30 x 10-13 J of energy. Find out the velocities of the two α particle that arises from the decay of a 4Be nucleus at rest; assume that all the energy appears as kinetic energy of the particles.
