The position of a particle is r(t) = (2.5t²☎ + 4ỹ − 4t2) m. a. Determine its velocity and acceleration as a function of time. v(t) = 5t x + 0 ŷ + 4t x 2) m/s ✓ Correct! ✓ Correct! Is this the correct direction? ä(t) = 5 ✓ Correct! Correct! * Incorrect. a(t = 0) b. What are its velocity and acceleration at time t = 0? v(t = 0) = 0 X Select an answer m/s = ✓x + 0 Submit
Question ✓ŷ + 2) m/s² Select an answer ✓ m/s² Hint 1
