A. 3600 N
B. 4000 N
C. 3000 N
D. 2400 N

Answer

3600 N

Explanation

The resultant force can be calculated using Newton's second law, F = m x a. Here, the mass is 1200 kg and the acceleration is 3 m/s², resulting in a force of 3600 N.

Common mistake

Common Mistake in Resultant Force Calculation

Students often confuse the formula for calculating resultant force, mistakenly using the equation for acceleration instead.

Remember that the correct formula is F = m x a, where F is the resultant force, m is mass, and a is acceleration. Ensure to use the correct variables when performing calculations.
