Time rate of change of position vector

WebThe position vector of a moving particle in x − y plane can be represented as → r = (2 t ˆ i + 2 t 2 ˆ j) m, where t represents the time instant. The rate of change of θ at time t = 2 s. (where θ is the angle which its velocity vector makes with positive x − axis) WebJan 27, 2024 · So grad ( T) is − 1 6 3 ( 1, 1, 2). The unit vector in the direction Q R is 1 3 ( − 1, − 1, − 1). So to get the rate of change in that direction we take the dot product to get. 1 18 ( 1 + 1 + 2) = 2 9 = 0.2222 …. Your answer was wrong because you took the rate of change in the direction Q O instead of Q R.
