🧠  Means Constant Acceleration

Read the question.  in m/s. Mass = . Find force.

This is exactly the same template as NLM-030. The principle: when  is given as a function of , use . And for the specific form , the acceleration is constant, equal to .

🗺️ Working It Out

.

Notice  cancels — acceleration is constant.

Force: .

⚡ The Smart Move

The pattern:  comparing with  (starting from rest), , so .

For NLM-030: .

For NLM-035: .

In one line, no calculus needed. Just identify  (the
