A jet plane is launched from a catapult on an aircraft carrier. In 2.0 s it reaches a speed of 42 m/s at the end of the catapult. Assuming the acceleration is constant, how far did it travel during those 2.0 s?

Explanation:

Given

time taken

Speed acquired in 2 sec

Here initial velocity is zero

acceleration is the rate of change of velocity in a given time

Distance travel in this time

where  

s=displacement

u=initial velocity

a=acceleration

t=time

so Jet Plane travels a distance of 42 m in 2 s                                

ill do it for 100, also this isnt 80 its 40

it takes about 30 days for it to break down
