Question

Acceleration/Velocity/Position type problem

Answer 1

first write down thing those are given

Answer 2

final velocity of the car
\[V_{f}=0\\ intial ~velocity,V_{initial}=u ~have ~To ~find\\\\distence~travelled=d=180\\acceleration=a=-10 ft/s^2(as~\it~slows~down)\\now ~use\\v_f^2=V_{initial}^2+2.a.d\\0=v_{initial}^2-2*10*180\]
now solve for v(initia)
