Q1 (2 points) Suppose we have two vectors, ~u and ~v, and their moduli are the same. Is it possible that the modulus of ~u + ~v is equal to the modulus of ~u? Is it possible that the modulus of ~u ~v is equal to the modulus of ~u? Explain your answer with a drawing. Q2 (2 points) Someone standing well above the ground throws two balls with initial velocities of the same modulus, one up and the other down. Without taking into account the resistance of the air, which has the greatest speed just before hitting the ground?
