Math Problem Statement
A crate slides across a frictionless horizontal surface with constant acceleration 4.70 m/s2 and over a time interval reaches a final velocity of 13.2 m/s. (a) If its initial velocity is 6.60 m/s, what is its displacement (in m) during the time interval? (Indicate the direction with the sign of your answer.) 13.84
Correct: Your answer is correct. m (b) What is the distance it travels (in m) during this interval? 13.84
Correct: Your answer is correct. m (c) If its initial velocity is −6.60 m/s, what is its displacement (in m) during the time interval? (Indicate the direction with the sign of your answer.) 13.81
Correct: Your answer is correct. m (d) What is the total distance it travels (in m) during the interval in part (c)?
