KINEMATICS VECTORS Position, displacement, velocity, acceleration vectors PHYSICS Solved Exercises
How to calculate the position vector, displacement, instantaneous velocity, average velocity, instantaneous acceleration, and average acceleration. Vectors in Physics (1st year of high school, 2nd year of high school, university). Problem solved step by step. We will also take the opportunity to review derivatives, vectors, kinematics, and motion.
Problem Statement: Let the position vector be r(t) = (t^2 + t + 1)i + (t - 3)j m. Calculate:
a) The displacement between t = 0 s and t = 2 s
b) The average velocity between t = 0 s and t = 2 s
c) Instantaneous velocity
d) Average acceleration between t = 0 s and t = 2 s
e) Instantaneous acceleration
