A projectile fired from a gun has initial horizontal and vertical components of velocity equal to 30m/s and 40m/s, respectively. a. At what angle is the projectile fired (measure with respect to the horizontal)? b. Approximately how long does it take the projectile to reach the highest point in its trajectory? c. What is the speed of the projectile when it I at the highest point in its trajectory? d. What is the acceleration of the projectile when it reaches its maximum height?
