The acceleration, velocity, and position vectors of an object moving in x-y plane are given by the following expressions respectively.
a = (4t - 2) i + (-2t2 + 4) j (ft/s2)
v = 6 i + 8 j (ft/s)
r = 3 i - 2 j (ft)
What is the x-component velocity of the object at t = 3s?
What is the y-component velocity of the object at t = 3 s?
What is the x-position of the object at t = 3s?
