1). A car is moving along a straight line defined to be thepositive x direction. Its velocity is measured and found to be afunction of time given by Vx(t)=(alpha)t^2 , where alpha is a knownconstant. The car was at the point x = A at the time t = 2sec. Findthe car's position as a function of time. How fast would the car begoing just before it hits a wall located at x = L? (Give Law orDefinition. Give Application. Give Result.) (The professors answeris v(t*)= (alpha)((3(L+8alpha/3-A))/alpha)^2/3) Please give as muchexplanation as possible!
