Answer:
Explain. yes it is possible because when the net force is zero and acceleration is zero. ... no, Neglecting air friction, the only force acting on this object is the force of gravity downward. There is no force of equal magnitude as the force of gravity acting in the opposite direction.

V = 20 m/s
Ecin = 1.8 x 10^5 J
Ecin = m*v^2/ 2
1.8*10^5 = m*400/2
200m = 1.8*10^5
I know you can do it :)
Fg=m•g || IE: Weight = mass x gravity
Therefore, the relationship are as follows:
mass and gravity are inversely proportional
mass and weight are directly proportional
weight and gravity are directly proportional
Answer:
They are equal
Explanation:
angle of incidence = angle of reflection
