commencing-with-an-initial-velocity-of-120-ms-in-the-westward-direction-a-boat-a

Question

Commencing with an initial velocity of 12.0 m/s in the westward direction, a boat achieves a velocity of 18.5 m/s northward after a 6.00-second duration. Calculate the magnitude and direction of (i) the average velocity, (ii) the average acceleration throughout this interval, and (iii) the average speed.

Accepted Answer

i. the average velocity cannot be determined; ii. a_avg = 3.67 m/s²,57.0° north of west; iii. the average speed cannot be determined.

Answer

i. v_avg = 22.1 m/s, 57.0° west of north; ii. a_avg = 1.08 m/s²,57.0° west of north; iii. s = 30.6 m/s

Answer

i. v_avg = 22.1 m/s, 57.0° west of north; ii. a_avg = 1.08 m/s²,57.0° north of west; iii. the average speed cannot be determined.

Answer

i. the average velocity cannot be determined; ii. the average acceleration cannot be determined; iii. the average speed cannot be determined.
