Answer
given,
mass of the = m₁ = 8.75 Kg
another mass of the object = m₂ = 14 Kg
distance between them = 50 cm
R₁ = 17 cm
R₂ = 50 -17 = 33 cm
a) Force applied due to the Mass 8.75 in +ve x- direction
Force applied due to mass 14 Kg in -ve x-direction
net force
F = F₁ + F₂
Using newton second law
b) As the acceleration of mass comes out to be +ve hence, the direction will be toward the mass of 8.75 Kg
Answer:
A. The same amount
Explanation:
The acceleration at which objects free falls to the ground on Earth is constant and its value is always , regardless of their mass (in this problem we neglect air resistance).
So, it doesn't matter if the two rocks are different or they are launched from different heights: their acceleration will be exactly the same.
This can be proved this way: first of all, the force of gravity exerted on every object is equal to the weight of the object,
where m is the mass of the object and g the acceleration of gravity.
However, we also know for Newton's second law that
where a is the acceleration of the object.
Combining the two equations,
So, the acceleration of an object in free fall is exactly the acceleration of gravity.
