A ball is launched at an angle of 30.00 with the horizontal and an initial speed of 10.00 m/s from a table. Take g = 9.800 m/s- and use a coordinate system with the origin at the point at which the ball is launched and the x-axis horizontally forwards and the y-axis vertically upwards. In this coordinate system, using unit vector notation, write down values for the following quantities (simplify your answers as far as possible and don't forget units!) The initial position vector, r(0): The initial velocity, v(0): The acceleration vector of the ball as a function of time a(() =
