A horizontal rifle is fired at a bulls-eye the muzzle speed

Question

Find the correct formulation of the following problems-

Problem 1- On a spacecraft, two engines are turned on for 542 s at a moment when the velocity of the craft has x and y components of v_0x = 2960 m/s and v_0y = 5010 m/s. While the engines are firing, the craft undergoes a displacement that has components of x = 3.31 x 10⁶ m and y = 4.76 x 10⁶ m.

Part 1- Find the x components of the craft's acceleration.

Part 2- Find the y components of the craft's acceleration.

Problem 2-A horizontal rifle is fired at a bull's-eye. The muzzle speed of the bullet is 690 m/s. The gun is pointed directly at the center of the bull's-eye, but the bullet strikes the target 0.028 m below the center.

Part 1- What is the horizontal distance between the end of the rifle and the bull's-eye?

I need help to evaluate the above problem.
