Actually Welcome to the Concept of the Force.
Force = Mass * Acceleration.
here, Mass = 45 kg and Force = 65 N
hence, Acceleration = 65/45
===> Acc. = 1.44 m/s^2
hence the acceleration is 1.44 m/s^2
Answer:
the child is 1.581 m far from the fence
Explanation:
The diagrammatic illustration that give a better view of what the question denote can be seen in the image attached below.
From the image attached below, let assume that the release point is the origin, then equation of the motion (x) is as follows:

---- (1)
the equation of the motion y is :






By using the quadratic formula, we have;

where;
a = 4.9, b = -5.14 c = 1







In as much as the ball is traveling upward, then we consider t= 0.258sec.
From equation (1)




Thus, the child is 1.581 m far from the fence
One way that the world's ocean affects weather and climate is by playing an important role in keeping our planet warm. ... The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation.

Answer:
0
Explanation:
Weight = mass x gravity
if gravity = 0 then Weight =0 as well
