A baseball (a projectile) is launched from a height of 2 meters above the ground at a speed of 31 m/s at an of 28 degrees above the horizontal. The ball is directly hit a fielder who will catch the ball and the fielder is initially angle plate). If his reaction time is 0.30 seconds (time before he starts to move), what is the minimum speed he much run, in m/s, such that he catches the ball 2 meters above...
1. A projectile is launched horizontally from a height above level ground of 3 m. When it hits the ground, it's horizonta displacement from the launch point is 7 m. a. b. How much time does it spend in flight? With what speed was it launched? Suppose the projectile were now launched from the same point at an angle of 45 above the horizontal. a. b. How much time does it spend in the air? What is its horizontal displacement...
