It climbs the hill with constant velocity Assignment Status VI = VI,x i + vi,yj = (29 m/s) i + (6.6 m/s) j Click here for detailed view as indicated in the figure. The period of time during which the car changes its velocity is At = 3.3 s. Problem Status Completed Completed W N Completed 50% Part (a) Enter a symbolic expression for the average acceleration vector of the car during the given time period in terms of the variables in the 4 Completed problem and the standard unit vectors. 5 Completed dave = ( V1x - Vox ) i/At + Vly j/At Correct! 6 Completed 50% Part (b) What is the magnitude, in meters per squared second, of the car's average acceleration during the given time period. 7 Completed Grade Summary 8 Partia dave = 9.461 m/s2 Deductions 0% 9 Partial Potential 100% Late Work % 100% 10 Completed sin() cos() tan() 7 8 9 HOME Late Potential 100% 11 Completed cotan() asin acos() E 4 5 6 12 Completed Submissions atan acotan() sinh() * 1 2 3 Attempts remaining: 994 13 (0% per attempt) cosh() tanh() cotanh() + 0 END 14 detailed view .
