If no, explain why the calculation cannot be completed. 5 kg + 30 m/s b) Can the following arithmetic be completed? If yes, complete the arithmetic and give the answer. If no, explain why the calculation cannot be completed. 10 m + (13 m/s)(2 s) + 1/2(-9.81 m/s^2)(2 s)^2 c) What units will the following calculation have? Question 3: Answer the following: a) Can two vectors of unequal length add up to zero? Explain your answer fully, draw pictures to prove points. b) Can three vectors of unequal length add up to zero? Explain your answer fully, draw pictures to prove points.

2) a) No, because they have different dimensions

b) Yes,

10m +13 m/s*2s + 1/2 *(-9.81m/s^2)*(2s)^2

= 16.38 m

c) the calculation will have unit of s^-2 because other units kg and m get cancelled out
