A baseball has an initial speed of 90 ft/s. It travels northeast at an angle of 45° degrees above the horizontal. (1) What is the initial velocity of the baseball? Use: positive x (east), positive y (north), positive z (up). (2) What is the velocity of the baseball after 1.5 s? (Neglect all forces other than the gravitational force on the ball. Assume that the gravitational acceleration constant is 32 ft/s².) A baseball has an initial speed of 90 ft/s. It travels northeast at an angle of 45° degrees above the horizontal.
