A fireworks shell P fired in a vertical trajectory has acceleration given by ay=-g-k*(v^2). The first term in the relation is weight and the second term is due to drag force. The value of the drag parameter k is constant. At the moment shown in the figure, the velocity of the firework is Vp. Calculate the radius of curvature, normal, tangential and resultant acceleration values for this moment. First image is the wanted values and second image is the image of question. ( OA=140m, AP= 210m, k=0.025m^(-1), Vp=20m/s ). I have been trying to solve this question for so long but i couldn't figure it out. Please solve this question so i can understand how to solve this kind of questions.
