Sebuah partikel bergerak dengan komponen percepatan ax=(10t−2)ia_x=\left(10t-2\right)iax=(10t−2)i dan ay=(12−3t)ja_y=\left(12-3t\right)jay=(12−3t)j. Apabila komponen kecepatan awal (0; 0), maka persamaan kecepatan terhadap waktu adalah ... m/s.
v(t)=(5t2−2t)i+(12t−1,5t2)j v\left(t\right)=\left(5t^2-2t\right)i+\left(12t-1,5t^2\right)j\ v(t)=(5t2−2t)i+(12t−1,5t2)j
v(t)=(10t3−2t2)i+(10t2−16t3)j v\left(t\right)=\left(10t^3-2t^2\right)i+\left(10t^2-16t^3\right)j\ v(t)=(10t3−2t2)i+(10t2−16t3)j
v(t)=10i−3jv\left(t\right)=10i-3jv(t)=10i−3j
v(t)=(8t)i−(12t−3)jv\left(t\right)=\left(8t\right)i-\left(12t-3\right)jv(t)=(8t)i−(12t−3)j
v(t)=(19t−1)i+(15t2−3t)j v\left(t\right)=\left(19t-1\right)i+\left(15t^2-3t\right)j\ v(t)=(19t−1)i+(15t2−3t)j
