What is needed to give a larger boulder a large acceleration?
2 answers:
Answer:
Huge amount of force
Explanation:
As per Newton's 2nd law of motion the acceleration of an object is directly proportional to the force applied on it. it can be expressed as
Here the mass of the boulder is a lot. To give it large acceleration a huge amount of force will be needed to apply on it.

Answer:
A. 181.24 N
Explanation:
The magnitude of hte electrostatic force between two charged objects is given by the equation
where
k is the Coulomb's constant
q1, q2 are the magnitudes of the two charges
r is the separation between the charges
In this problem, we have:
is the magnitude of the 1st charge
is the magnitude of the 2nd charge
r = 2.5 cm = 0.025 m is the separation between the charges
Therefore, the magnitude of the electric force is:
So, the closest answer is
A) 181.24 N
