Question

An armadillo scurries along in a straight line (the r-axis). The equation for the armadillos position vector is t) = 150.0cm i + (12.0cm/s) t i-(0.480cm/s*)t, İ a. Determine the armadillos initial distance from the origin. 7. b. Determine the armadillos initial speed. c. Determine the armadillos initial velocity. d. Determine the armadillos acceleration e. alculate when the armadillo turns around and starts to scurry back the way it came. f. Calculate the time that elapses (starting fromt 0) until the armadillo returns to its starting position. Answer: 25 s. g. Calculate the velocity of the armadillo when it returns to its starting position h. Calculate the time it takes for the armadillo to reach a position of 200.0 cm aftcr it has turned around.
