Question 39

A hypersonic research drone is launched along a straight, horizontal electromagnetic rail.

The drone has an initial speed of 12 m/s at the start of the rail, and accelerates to a launch speed of 76 m/s at the end of the rail.

The constant acceleration of the drone during this launch phase is 22 m/s2.

Calculate the length of the rail, sss, required for the drone to reach its launch speed.

Use the equation:

s=v2−u22a s = \frac{v^2 - u^2}{2a} s=2av2−u2​
