1. The problem statement, all variables and given/known data A car, as shown in the figure, is going in a curvilinear road. The size of the car will be neglected. 2. Relevant equations Its acceleration is a = 0.5*e^t m/s^2. 3. The attempt at a solution If it goes 18 meters on its way, then calculate its velocity and acceleration. I have one more question. A particle is making linear action. Its velocity in the origin is 4 m/s. If particle is slowing down with acceleration a = -3/2*v^1/2 m/s^2, calculate the elapse time and its taking way until it stops(v=0). Hope I could explain my questions clearly. How can I calculate them? Please help me.
