A spacecraft on its way to Mars has small rocket engines mounted on its hull; one on its left surface and one on its back surface. At a certain time, both engines turn on. The one on the left gives the spacecraft an acceleration component in the x direction of a, = 5.10 m/s², while the one on the back gives an acceleration component in the y direction of a, = 7.30 m/s. The engines turn off after firing for 135 s, at which point the spacecraft has velocity components of vy = 3810 m/s and v, = 4168 m/s. What was the magnitude and the direction of the spacecraft's initial velocity before the engines were turned on? Express the magnitude as m/s and the direction as an angle measured counterclockwise from the +x axis. magnitude 3121.5 Note the acceleration is constant. What are the components of the acceleration? What constant acceleration relation will you need to find the final velocity components? m/s direction 45.5 ° counterclockwise from the +x-axis

A spacecraft on its way to Mars has small rocket engines mounted on its hull; one on its left surface and one on its back surface. At a certain time, both engines = 5.10 m/s2, while the one on the back gives an acceleration turn on. The one on the left gives the spacecraft an acceleration component in the x direction of a, component in the y direction of a, = 7.30 m/s. The engines turn off after firing for 135 s, at which point the spacecraft has velocity components of V, = 3810 m/s and v, = 4168 m/s. What was the magnitude and the direction of the spacecraft's initial velocity before the engines were turned on? Express the magnitude as m/s and the direction as an angle measured counterclockwise from the +x axis. magnitude 3121.5 Note the acceleration is constant. What are the components of the acceleration?
