Q: A 3 kg block is on a table and a horizontal force of 15 N is applied. If the frictional force is 5 N, what is the acceleration of the block?

Solution: Net force = applied force - friction = 15 N - 5 N = 10 N. Acceleration a = F/m = 10 N / 3 kg = 3.33 m/s².

Steps: 8

Step 1: Identify the mass of the block, which is 3 kg.
Step 2: Identify the applied force, which is 15 N.
Step 3: Identify the frictional force, which is 5 N.
Step 4: Calculate the net force by subtracting the frictional force from the applied force: Net force = 15 N - 5 N.
Step 5: Perform the subtraction: 15 N - 5 N = 10 N.
Step 6: Use the formula for acceleration, which is a = F/m, where F is the net force and m is the mass.
Step 7: Substitute the values into the formula: a = 10 N / 3 kg.
Step 8: Perform the division: 10 N / 3 kg = 3.33 m/s².
