please help me to do Q1- than kyou
F4/PHY /20-21/Yearly Exam /P.18 10 Two blocks P and Q of mass 1 kg and 1.5 kg respectively are connected by a light string passing over a smooth pulley. The incline is frictionless. The system is released when P is 1 m above the ground. 1 m Q 30⁰ (a) A student suggests that the potential energy lost by block P is converted into the kinetic energy of both blocks P and Q. Is he correct? Explain briefly. (2 marks) (b) Find the speed of blocks P and Q just before block P touches the ground. (c) After block P reaches the ground, how much further will block Q move up the incline before instantaneously coming to rest? (3 marks) (2 marks)
