AP Physics C: Mechanics
1.2 Displacement, Velocity, and Acceleration
1.1 Scalars and Vectors
An object moves in the \(xy\)-plane with an instantaneous velocity \(\vec{v} = (3.0\hat{\imath} - 4.0\hat{\jmath})\text{ m/s}\) and an instantaneous acceleration \(\vec{a} = (-2.0\hat{\imath} + 1.0\hat{\jmath})\text{ m/s}^2\). What is the instantaneous rate of change of the object's speed, \(\dfrac{dv}{dt}\)?
