Question

The particle travels along the path defined by the parabola y = 0.5$x^2$, where x and y are in ft. (Figure 1) Part A If the component of velocity along the x axis is $v_x = (3t)$ ft/s, where t is in seconds, determine the particle's distance from the origin @ t = 3 s. When t = 0, x = 0, y = 0. Express your answer using three significant figures and include the appropriate units. Figure y = 0.5x^2 d = 3.00 ft Incorrect; Try Again; 5 attempts remaining Part B Determine the magnitude of its acceleration when t = 3 s. Express your answer using three significant figures and include the appropriate units. Value Units

y = 0.5$x^2$, where x and y are in ft.
(Figure 1)
Part A
If the component of velocity along the x axis is $v_x = (3t)$ ft/s, where t is in seconds, determine the particle's distance from the origin @ t = 3 s.
When t = 0, x = 0, y = 0.
Express your answer using three significant figures and include the appropriate units.
