A 20 kg cart is pulled with a force of 80 N. If the frictional force is 20 N, what is the acceleration of the cart? (2020)

A 20 kg cart is pulled with a force of 80 N. If the frictional force is 20 N, what is the acceleration of the cart? (2020)

Step 1: Identify the total force applied to the cart, which is 80 N.
Step 2: Identify the frictional force acting against the motion, which is 20 N.
Step 3: Calculate the net force by subtracting the frictional force from the total force: 80 N - 20 N = 60 N.
Step 4: Identify the mass of the cart, which is 20 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 = 60 N / 20 kg.
Step 7: Calculate the acceleration: a = 3 m/s².

Newton's Second Law – The relationship between force, mass, and acceleration, expressed as F = ma.
Net Force Calculation – Understanding how to calculate net force by subtracting friction from the applied force.
Frictional Force – Recognizing the role of friction in opposing motion and its effect on net force.
