Question

A force of 360 N is applied to a 90 kg mass on a surface with friction. What is the acceleration of the mass?

(A) 4 m/s^2
(B) 2 m/s^2
(C) 1 m/s^2
(D) 0.5 m/s^2

Answer 1

The acceleration of a 90 kg mass with a force of 360 N applied to it is 4 m/s^2, assuming friction is not considered.

Step-by-step explanation:

The question is asking to calculate the acceleration of a mass given the force applied and taking into account the frictional force. To solve this problem, we need to apply Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (a = F/m). However, the question does not provide the frictional force value. Assuming the question intends to calculate the acceleration without considering friction, the acceleration would be a = F/m.

Using the given values:

• Force (F) = 360 N
• Mass (m) = 90 kg

The acceleration (a) can be calculated by dividing the force by the mass:

a = F / m = 360 N / 90 kg = 4 m/s2

Therefore, the correct answer is (A) 4 m/s2.
