Question

A car with an initial velocity of 24.5 m/s east has an acceleration of 42 m/s2 west. What is its displacement at the moment that its velocity is 18.3 m/s east?​

Answer 1

vf^2=vi^2+2ad -> 18.3^2 = 24.5^2 + 2*-42*d ->

334.89 = 600.25 - 84d -> -265.36 = -84d ->

3.159 = displacement = answer
