(10%) Problem 13: Two cars are heading towards one another. Car A is moving with an acceleration of a = 11 m/s². Car B is moving with an acceleration of ag = -1 m/s². The cars are initially at rest and separated by a distance d = 2600 m on the x-axis. ▷ 25% Part (a) At what time, in seconds, do the cars meet? t = -22.80| Grade Summary Deductions Potential 0% 100% tan() π 7 8 9 HOME sin() cotan() 4 5 6 Submissions Attempts remaining: 16 (0% per attempt) + acos() EM^^ sinh() cotanh() * / cos() asin() acotan() tanh() Degrees O Radians → 1 2 3 atan() cosh() detailed view + 0 END 1 0% - 2 0% VO BACKSPACE DEL CLEAR 3 0% 4 0% Submit Hint Feedback I give up!
