    That's too simple. If we were to use F=ma, acceleration would most likely be -9.8 m/s^2. then that would be 5.10 *10^6N/ -9.8m/s^2 But what is the time used for??? We were given this equation: X(final) = X(initial) + velocity of x * time + .5(acceleration)(time^2) Where we are confused is...

    Been struggling wih this problem all afternoon. On an aircraft carrier, a jet can be catapulted fom 0 to 155 mi/hr in 2.00 sec. If the average force exerted by the catapult is 5.10 * 10^6 Newtons, what is he mass of the jet? We converted the velocity into meters/second and got 69.276...
