Nothing great will ever be achieved without great men, and men are great only if they are determined to be so. For glory gives herself only to those who have always dreamed of her. – Charles De Gaulle

00:52:39 Example 4.5 A particle starts from origin at t = 0 with a velocity 5.0 î m/s and moves in x-y plane under action of a force which produces a constant acceleration of (3.0i+2.0j) m/s^2. (a) What is the y-coordinate of the particle at the instant its x-coordinate is 84 m ? (b) What is the speed of the particle at this time ?
