Activity 1.16- Projectile Motion Problems Note: Neglect air friction unless otherwise specified. Use g = +10 m/s² for the magnitude of the acceleration due to gravity. 1. You throw a snowball from a roof with a speed of 20 m/s at an angle of 36.87" above the horizontal. The ball lands at a horizontal distance of 48 meters from where you throw the snowball. Assume free fall. a. Use the diagram below and problem statement above to complete the table. Write in values if given in the problem statement (or easily calculated). Use a question mark if the value is not given in the problem statement. Use the origin and +x and ty directions shown. Ya 16-20 (0,0) ! +y 9 = 36.87 48 m Vaz- x= V₂ = b.
