A bullet is fired with a certain velocity at an angle θ above the horizontal at a location where g = 10.0 m/s². The initial x- and y-components of its velocity are 86.6 m/s and 50.0 m/s respectively. What is the initial velocity of the bullet? A) 86.6 m/s B) 50.0 m/s C) 36.6 m/s D) 100 m/s E) 136 m/s

Question

Quizplus · Accepted Answer

The initial velocity of the bullet can be found using the Pythagorean theorem: v = √(vx² + vy²) = √(86.6² + 50.0²) = 100 m/s.
