Answer:
The center of mass for the object is from the origin
Explanation:
From the question we are told that
The mass of the first object is
The position of first object with respect to origin
The mass of the second object is
The position of second object with respect to origin
The mass of the third object is
The position of third object with respect to origin
The mass of the fourth object is
The position of fourth object with respect to origin
Generally the center of mass of the object along the x-axis is zero because all the mass lie on the y axis
Generally the location of the center mass of the object is mathematically represented as

Answer:
The acceleration is about 9.8 m/s2 (down) when the ball is falling.
Explanation:
The ball at maximum height has velocity zero
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.8 m/s² (positive downward and negative upward)
The accleration 9.8 m/s² will always be acting on the body in opposite direction when the body is going up and in the same direction when the body is going down. The acceleration on the body will never be zero
