Ajet fighter plane is launched from a catapult on an airaraft carrier. it reaches a speed of 42 mis at the end of the catapult, and this requires 2.0s. assuming the acceleration is o 63 m o 24 m o 84 m o 42 m o 16 m

s = 42 meters                            

Explanation:

Initial speed of the jet, u = 0

Final speed of the jet, v = 42 m/s

Time taken, t = 2 s

Let a is the acceleration of the jet. It can be calculated using equation of kinematics as :

It is assumed that the acceleration of the jet is constant. We can find the length of the catapult. It is given by s.  

s = 42 meters

So, the length of the catapult is 42 meters. Hence, this is the required solution.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
