Chapter 10, Problem 51RCQ
A projectile is fired straight upward at 141 m/s. How fast is it moving at the instant it reaches the top of its trajectory? Suppose that it were fired upward at 45° instead. Then its horizontal component of velocity would be 100 m/s. What would be the speed of the projectile at the top of its trajectory?
