(b) A person throws a paper ball from a height of 4m from the ground. The wind is blowing and the acceleration is given by 2/3 a(t) = ( 12v3t? – 24t + (12/5P - ) -6 for t> 0. 3 7 (0), is thrown with an initial velocity of magnitude 4m/s at an angle 0 = rad with respect to the horizontal. All measurements are in SI units. me 3 rad 4 m basket
