Question: A force of 15 N is applied to a 3 kg object. What is the object\'s acceleration?
Options:
3 m/s²
5 m/s²
7 m/s²
10 m/s²
Correct Answer: 5 m/s²
Solution:
Using F = ma, acceleration a = F/m = 15 N / 3 kg = 5 m/s².
A force of 15 N is applied to a 3 kg object. What is the object's acceleration?

Questions & Step-by-Step Solutions
A force of 15 N is applied to a 3 kg object. What is the object's acceleration?
Step 1: Identify the force applied to the object. In this case, the force is 15 N.
Step 2: Identify the mass of the object. Here, the mass is 3 kg.
Step 3: Use the formula for acceleration, which is a = F/m, where F is the force and m is the mass.
Step 4: Substitute the values into the formula: a = 15 N / 3 kg.
Step 5: Calculate the acceleration: 15 N divided by 3 kg equals 5 m/s².
Newton's Second Law of Motion – This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
