Q14. As shown in the image below, the force acting on the box is F = (C · t²) N, where constant C = 3 and tis time in s. Determine the magnitude of the total impulse (in N-s) done by force Fto the box during the period from t= 0 to t= 1.4 s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. F 4 Your Answer: Answer

Please provide handwritten answer

2. A particle on a damped spring has an acceleration of x = -5x -0.2x. It has an initial position of x(0) m = 2 m and an initial velocity of x (0) = 3. Find the position and velocity at t = 4 s. Assume all values are given to three significant figures. Please use any method learned in class: Trial Solution Method, Euler Method, or Laplace Transformation. Show all work.
