A 2 kg object undergoes an acceleration given by a = (4 i - 5 j) m/s?. The resultant force (in N) acting on the object is O a. 8 i- 10 j O b. 8 i O c- 10 j O d. 8 i + 10 j Question 5 A 0.2 kg object is swung in a vertical circular path on a light string 0.4 m long. If its speed is 6 m/s at the top of the circle, what is the tension in the string there?
