8 The diagram shows four identical spheres placed between two wooden blocks on a ruler.
1 answer:
The diameter of the sphere is 2cm.
<h3>How to calculate the diameter?</h3>From the diagram, the first sphere on the ruler is at 4cn and the last sphere is at 12cm.
Therefore, the length will be:
= 12 - 4.
= 8cm
The diameter of one sphere will be:
= Length / 4
= 8/4
= 2
Therefore, the diameter of the sphere is 2cm.

the parabolic movment is described by the following equation:
where y is the height of the ball, a is the angle of launch, the initial velocity, g the gravity and x is the horizontal distance of the ball.
So, if we want that the ball reach the hood, we will replace values on the equation as:
Finally, solving for , we get:
