A 1200 kg car travels round a bend of radius 50 m at 15 m/s. What is the centripetal force needed?
Answer and explanation
Correct answer: C. 5400 N
- Step 1: . Step 2. N. Answer: 5400 N. Why not the others: 360 N uses ; 2700 N includes a factor from kinetic energy; 270 000 N is without dividing by r.
