A car moves with a constant accelaration of "a" from the initial values of t=0s, x,(position)and V, (velocity). The equation of motions define as followings. Please draw the graphs of displacement, velocity and accelaration changes by time. 9 = 0, + ato = 0, + at x = x, + 0,t +at°x = x, + 0,t +at?

A baseball is hit towards the outfield, following the equations x(t)=51.5t and y(t)=−16t^2+105t+4, where x and y are measured in feet and t is time measured in seconds. A. How long does it take for the ball to hit the ground? Round your answer to the nearest second.  Show your work.   B. How far has the ball traveled (horizontally) when it hits the ground? Round your answer to the nearest foot.  Show your work.   C. Eliminate the parameter by writing the parametric equations as a single rectangular equation.  Show your work.

Figure below shows two vectors, P and Q. Based on the information provided in the picture determine the magnitude of a vector R =-2P+2Q. 10 Ō Assume each square on the grid is equivalent to one unit and that the components of the vectors are provided with the precision to the nearest integer. Round your answer to one decimal place.
