A car of mass 50 kg accelerates at 6 m/s squared. What is the resultant force on it?
Answer and explanation
Correct answer: C. 300 N
- Step 1: Force = mass x acceleration.
- Step 2: 50 x 6 = 300 N.
Answer
300 N.
Why not the others: 8.333 N: the mass was divided by the acceleration. 56 N: the mass and acceleration were added. 3000 N: the weight factor 10 was multiplied by mistake.
