QUESTION 1 A football is kicked into the air at an angle of 45 degrees with the horizontal. At the very top of the ball's path, the net force acting upon it is _ _ (Neglect the effects of air resistance.) entirely vertical O entirely horizontal both vertical and horizontal not enough information given to know QUESTION 2 At what point in its path is the horizontal component of the velocity (vx) of a projectile the smallest? O A. The instant it is thrown. O B. Halfway to the top. O C. At the top. O D. As it nears the top. O E. It is the same throughout the path. QUESTION 3 Two projectiles are fired at equal speeds but different angles. One is fired at angle of 30 degrees and the other at 60 degrees. The projectile to hit the ground first will be the one fired at (neglect air resistance) 30 degrees O 60 degrees O both hit at the same time QUESTION 4 A projectile is launched with an initial speed of 21.8 m/'s at an angle of 35.0-degrees above the horizontal. (=) Determine the time of flight of the projectile. (b) Determine the peak height of the projectile. (c) Determine the horizontal displacement of the projectile.
