Answer:
<h3>The answer is 2 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

where
f is the force
m is the mass
From the question
f = 20 N
m = 10 kg
We have

We have the final answer as
<h3>2 m/s²</h3>
Hope this helps you
Answer:
45 j
Explanation:
At the top, the KE will have been converted to PE
KE = 1/2 mv^2 =PEat-top = 1/2 10 *3^9 = 45 j
Refer to the diagram shown below.
The force, F, is applied at 5 cm from the elbow.
For dynamic equilibrium, the sum of moments about the elbow is zero.
Take moments about the elbow.
(5 cm)*(F N) - (30 cm)*(250 N) = 0
F = (30*250)/5 = 1500 N
Answer: 1500 N
Since unbalanced forces acts on the spheres, the aim of increasing the release distance of the spheres is to observe the effect of unbalanced forces acting on the spheres.
<h3>What is an experiment?</h3>
An experiment is a study whose objective is to study cause and effect relationships. In this case, the students had to increase the distance at which the spheres was released.
The aim of increasing the release distance of the spheres is to observe the effect of unbalanced forces acting on the spheres.
