Question

If force A is 4 N and the mass of the dog is 2 kg, what will be the acceleration of the dog? (A) There will be no acceleration because Force A and Force B are equal. (B) 8 m/s^2 (C) 2 m/s^2 (D) 1/2 m/s^2.

Answer 1

(C) 2 m/s²

Step-by-step explanation:

Given that,

The force of the dog, F = 4 N

The mass of the dog, m = 2 Kg

The acceleration of the dog, a = ?

The force acting on a body is defined as the product of its mass 'm' that causes an acceleration 'a' in the body.

The relation between them is given by the equation

F = m x a newton

∴ a = F / m

Substituting the given values in the above equation,

a = 4 N / 2 Kg

= 2 m/s²

Hence, the acceleration of the dog is, a = 2 m/s²
