! COMPLETE SOLUTION !pls answer NO. 17*draw FBD*use data given below properly 16. The trajectory of a rocket makes an angle of 200 degrees below the horizontal when it is movingat 5,400 m/s. The thruster engine gives it a constant horizontal acceleration of 6 m/s^2 and thedownward acceleration is the acceleration due to gravity, Determinea. The rate at which the speed is changingb. The normal accelerationc. The radius of curvature17. A certain rifle has a muzzle velocity of 490 m/s. The rifle is pointed vertically upward and firedfrom an automobile moving horizontally at a speed of 19.6 m/sa. Determine the radius of curvature of the path of the bullet at its maximum altitudeb. How far has the car traveled at this instantc. Where will the bullet strike the ground18. A car starts from rest at a point A and increases its speed at a constant rate as it enters a curve.The magnitude of the total acceleration of the car as it passes point B, which is 400/3m alongthe curve from point A, is 2.5 m/s^2. The radius of curvature at point B is 200ma. Determine the normal component of the acceleration at point Bb. Determine the tangential component of the acceleration at point Bc. If the tangential acceleration at point B is directed downward to the right at an angle of36.87 degrees below the horizontal, and the normal acceleration is also directeddownward, determine the rectangular components of the acceleration at point B.19. A particle which moves along the curved path shown decelerates at a rare proportional to thedistance, measured along the curve, from point 0. It passess point 0 with a speed of 10 m/s andslow down to 8 m/s at point A in a distance of 12m, measured along the curve from point 0. Themagnitude of the total acceleration of the particle is 5 m/s^2 as it passes point A. Determine:tangent line to the curve at pointpath3a. The normal component of acceleration at point Ab. The tangential component of acceleration at point Ac. The radius of curvature of the pat at Ad. The rectangular components of the acceleration at point A20. Determine the force P that will give the body an acceleration of 0.5g m/s^2/ The coefficient ofkinetic friction is 0.35

ux = 19.6m/s uy = 490m/s θ = tan-1(uy/ux) = tan-1 (490/19.6) =87o42'34" U = ux2+uy2 = 490.392m/s
