A particle moving in the x-y plane has a velocity at time t = 5.92 s given by (3.3i + 6.4j) m/s, and at t = 6.02 s its velocity has become (3.53i+ 6.61j) m/s. Calculate the magnitude a of its average acceleration during the 0.10-s interval and the angle it makes with the x- axis. Answers: a = 0= i i m/s²

A fly walks with a speed of 1 cm/sec in every direction of a piece of paperwhich is considered to be xy plane. If the fly walks away from the origin inthe direction of u = i − 7j, the temperature it measures increases at a rateof 3◦C/sec. If the fly walks away from the origin in the direction v = i + j,the temperature it measures decreases at a rate of 2◦C/sec. Find how fast thetemperature changes if the fly moves away from the origin in the positive x axisdirection.

Your answer is partially correct. The velocity of a particle moving in the x-y plane is given by (7.70i + 4.91j) m/s at time t = 7.38 s. Its average acceleration during the next 0.029 s is (3.3i + 2.6j) m/s?. Determine the velocity v of the particle at t = 7.409 s and the angle 8 between the average- acceleration vector and the velocity vector at t = 7.409 s. Answers: v = ( 7.7957 i+ 4.9754 j) m/s 5.73

The velocity of a particle moving in the x-y plane is given by (5.00i + 7.38j) m/s at time t = 3.87 s. Its average acceleration during the next 0.014 s is (2.9i+2.6j) m/s². Determine the velocity v of the particle at t = 3.884 s and the angle between the average- acceleration vector and the velocity vector at t = 3.884 s. Answers: v = ( i e = i i+ i j) m/s
