66. Useful background for this problem can be found in Multiple- Concept Example 2. On a spacecraft two engines fire for a time of 565 s. One gives the craft an acceleration in the x direction of a, = 5.10 m/s², while the other produces an acceleration in the y direction of a, = 7.30 m/s². At the end of the firing period, the craft has velocity components of = 3775 m/s and v, = 4816 m/s. Find the magnitude and direction of the initial velocity. Express the direction as an angle with respect to the +x axis.

66. Useful background for this problem can be found in Multiple-
Concept Example 2. On a spacecraft two engines fire for a time of 565 s.
One gives the craft an acceleration in the x direction of a, = 5.10 m/s²,
while the other produces an acceleration in the y direction of a, = 7.30 m/s².
At the end of the firing period, the craft has velocity components of
= 3775 m/s and v, = 4816 m/s. Find the magnitude and direction
of the initial velocity. Express the direction as an angle with respect to
the +x axis.
