Question

titemID 2494993&enrollmentID; 239501 1 2 3 4 5 6 7 Acar is traveling around a horizontal circular track with radius r m as shown. takes the car t -58 s to go around the track once. The angle eA 33 above the x axis, and the angle ee 61' the axis. 1) What is the magnitude of the car's acceleration? m/s Submit 2.353 Your submissions: 2.353 X Computed value: 2.353 submitted: Monday, March 6 at 1:15 AM 2) what is the x component of the car's velocity when it is at point A Submit t of the car's velocity when it is at point A 3) What is the y componen m/s Submit 4) What is the x component of the car's acceleration when it is at point B m/s submit 5) What is the y component of the car's acceleration when it is at point B

Explanation / Answer

a) a=v^2/ R

v = 2pir/ T = (2x 3.14 x 190)/ 58 = 20.57 m/s apprx

a= 20.57^2/ 190 = 2.227 m/s^2

b) Vx ( A) = 20.57 cos 33= 17.25 m/s apprx

c) Vy (A) = 20.57 sin 33= 11.203 m/s apprx

d) ax( at point B) = 2.227 cos 61= 1.079 m/s^2

e) ay (a t point B) = -2.227 sin 61= -1.9478 m/s^2

all the answers are in approximation
