1.	A particle moves in the plane according to the law x=klt, y=kt(1-alphat), when k and alpha are positive constants, and t is the time, Find: a. the equation of the particle's trajectory y(x) (b) the velocity v and the acceleration a of the point as a function of time.
Answer» Answer :a. `y=x-alpha(x^(2))/(K^(2))`; (b) veca=(dvecv)/(DT)=2alpha k hatj`
