Q1. On a spacecraft, two engines are turned on for 702 s at a moment when the velocity of the craft has x and y components of velocity v0x = 3290 m/s and v0y = 5105 m/s. While the engines are firing, the craft undergoes a displacement that has components of x = 4.00 106 m and y = 6.60 x10^6 m. Find out the x and y components of craft's acceleration.
Q2. Vector A has a magnitude of 10m and makes an angle of 78o with the positive x axis. Vector B also has a magnitude of 13m and is directed along the negative x axis. Enter your answers in distance then angle (in degrees).
Find A + B
