010 10.0 points Initially (at time t = 0) a particle is mov ing vertically at 7.6 m/s and horizontally at 0 m/s. Its horizontal acceleration is 1.2 m/s2 . At what time will the particle be traveling at 45 with respect to the horizontal? The acceleration due to gravity is 9.8 III/S2 . Answer in units of s. 017 10.0 points A golf ball is hit at ground level. The ball is observed to reach its maximum height above ground level 5.3 s after being hit. 0.67 s after reaching this maximum height, the ball is observed to barely clear a fence that is 333 ft from where it was hit. The acceleration of gravity is 32 ft / s2 . How high is the fence? Answer in units of ft. 7135.

The student throws a ball along a path that she judges to make an initial angle of 6 with the horizontal and to be in line with the track. The student '3 professor, who is standing on the ground nearby, observes the bail to rise vertically How high does the ball rise? schwarz (srs5467) Homework 2- Vectors and 2D Motion perry (55910) 4 o2 1.h=1tan29 29 o2 2.h=1tan29 10. h, = sinE} cost} 023 10.0 points A __ ___.L! _1_ !_ ___ __ ___L 7. 10 m/s2 8. 500 m/s2
