Define
u = 16 m/s, the vertical launch velocity
g = acceleration due to gravity, measured positive downward
s = vertical distance traveled
t = 21.2 s, total time of travel.
The vertical motion obeys the equation
s = ut - (1/2)gt²
When the rock is at ground level, s = 0.
Therefore
(16 m/s)(21.2 s) - 0.5*(g m/s²)*(21.2 s)² = 0
339.2 - 224.72g = 0
g = 1.5094 m/s²
Answer:
The acceleration due to gravity is 1.509 m/s² measured positive downward.

Answer:
4 and 6 are true
Explanation:
Let's analyze we use Gauss's law every situation presented
R1. False The sphere is insulating, so the entire charge is evenly distributed throughout the volume, but the sign of the charge does not change.
R2. False In a conductor the entire charge is on the surface, therefore the electric field inside is zero, in an insulating sphere the electric field as the charge is distributed the field is proportional to the charge inside the Gaussian surface
R.3. False in a metallic sphere the charge is on the surface, by gauss law, inside it there is no charge, or therefore there is no electric field
R4 True. The electric field is as if all the charge were at the origin and the field lines have the same direction of the radii of the sphere that are perpendicular to the surface
R5 False In a metallic sphere the entire charge is on the surface, so the field is zero inside, instead a point charge has a non-zero field
R6 True. The load is on the surface
