Q
Q: A 12 kg object is pulled with a force of 48 N. If the frictional force is 12 N, what is the acceleration of the object? (2023)
Solution:
Net force = 48 N - 12 N = 36 N. Acceleration a = F/m = 36 N / 12 kg = 3 m/s².
Steps: 7
Show Steps
Step 1: Identify the total force applied to the object, which is 48 N.
Step 2: Identify the frictional force acting against the motion, which is 12 N.
Step 3: Calculate the net force by subtracting the frictional force from the total force: 48 N - 12 N = 36 N.
Step 4: Identify the mass of the object, which is 12 kg.
Step 5: Use the formula for acceleration, which is acceleration (a) = net force (F) / mass (m).
Step 6: Substitute the values into the formula: a = 36 N / 12 kg.
Step 7: Calculate the acceleration: a = 3 m/s².
