The characteristic of a circuit actually indicate how the circuit functions. When one designs a circuit they have a specific function in mind and must know how to combine components in order to fulfill this functions.
1) 211m/s
2)240<span>°
3)759,600m or 759.6 km</span>
If its accelerating it will increase velocity in the direction of the acceleration which is perpendicular to the velocity.
Time=speed/acceleration
Gravitaional Acceleration=9.8 m/s^2
Speed=24.5 m/s
Time=24.5/9.8=2.5 s
