Q. A particle with a mass of 1.6 × 10-20 kg is oscillating with simple harmonic motion with a period of 3.5 × 10-5 s and a maximum speed of 1.8 × 103 m/s. Calculate (a) the angular frequency and (b) the maximum displacement of the particle.
Q. Two cars have a head-on collision. Both were traveling at 42 m/s toward each other. Car A has a mass of 722 KG. Car B has a mass of 848 KG. After impact, car A is moving backward at 2 m/s. What is car B's velocity after impact?
