Messi is keeping his free-kick skills sharp this quarantine by playing football with his neighbour's monkey. From the roof of his house, which is 7 meters above the ground, he kicks a ball horizontally towards his neighbour's house, which is 6 meters away and also has a roof that is 7m above the ground. At the same instance, his neighbour's pet monkey drops off the ledge of his roof to try to catch the ball. Please ignore air resistance, and take g = 9.81m/s²

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.
