1. The problem statement, all variables and given/known data Suppose the position of an object is given by r⃗ = (3.0t2i^ - 6.0t3j^)m. Where t in seconds. Determine r⃗ at time t = 2.5 s. Express your answer using two significant figures. Express your answer in terms of the unit vectors i^ and j^. 2. Relevant equations plugging in 2.5 seconds to the r equation 3. The attempt at a solution r = 3(2.5)^2i-6(2.5)^3j -> 18.75i-73.002j -> 19i-73j When I put this answer in my homework, it says it's wrong. I even tried (19i-73j) and it says it's wrong.
