Question

The equation r (t) = (2t+9)i + (squared root of 3.t)j + (t²) k is the position of a particle in space at time t.

Find the angle (in radians) between the velocity and acceleration vectors at time t=0.

The equation r(t) = (2t + 9) i + (√3t) j+ (1²) k is the position of a particle in space at time t.

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
