TT Two airplanes leave an airport at the same time. The velocity of the first airplane is 750 m/h at a heading of 33.5. The velocity of the second is 600 m/h at a heading of 135. How far apart are they after 2.5 h? Answer in units of m.Initially (at time t = 0) a particle is mov ing vertically at 7.2 m/s and horizontally at 0 m/s. Its horizontal acceleration is 1.1 m / s2 . At what time will the particle be traveling at 33 with respect to the horizontal? The acceleration due to gravity is 9.8 m/s2 . Answer in units of s. A golf ball is hit at ground level. The ball is observed to reach its maximum height above ground level 4.5 s after being hit. 1.2 s after reaching this maximum height, the ball is observed to barely clear a fence that is 417 ft from where it was hit. The acceleration of gravity is 32 ft / s2 . How high is the fence? Answer in units of ft
