A ball is thrown vertically upwards. Air resistance is negligible. What is the variation with time t of the kinetic energy Ek of the ball?
Question
Solution 1
The kinetic energy (Ek) of an object is given by the equation Ek = 1/2mv^2, where m is the mass of the object and v is its velocity.
When a ball is thrown vertically upwards, its velocity decreases as it ascends due to the force of gravity. At the peak of its trajectory, its velocity is momentarily Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
