a jet fighter plane is launched from a catapult on an aircraft carrier. it reaches a speed of 42 m/s at the end of the catapult in 2 sec. if the acceleration is constant, what is the length of the catapult?

Answer 1

vf^2=2*acceleration*distance

solve for acceleration

Answer 2

Use the formula V=change in distance/chance in time

Equation looks like this:

42m/s= x/2

solve for x
