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.

Respuesta :

Answer:

(C)  2 m/s²

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
