a small 2 seat prop like a cub can be 80 knots
The aeroplane takeoff is controlled by the engine speed and the elevators.
Generally for a small Cessna 152 the rotation speed is 50 kias. For larger jets I am not sure but it's a start
137knots as an average
A small Cub needs approx 80 knots whilst an A380 can lift at 140.
This depends on the type of aeroplane. In the case of a VTOL jet the speed is actually zero.
"V1" is the speed at which the flight crew must either continue with the takeoff or abort the takeoff. It is the last point at which aborting is an option.
It's a measure of speed. (Like miles per hour (mph), or kilometers per hour (kph)). The Cessna 172 has a takeoff speed of about 55 knots (kts). A Boeing 737 has a takeoff speed of about 135-140 knots. On takeoff, aircraft need to reach a certain speed to get into the air.
they help an airplane bank (turn) after they takeoff
Rotational speed is the propeller slipstream and engine torque all contrive to make the airplane turn left during takeoff.
