I guess use a high speed camera
Time it and measure the distance travelled.An anemometer is used to measure wind speed. A Pitot Tube is used to infer speed in an aeroplane,. A speedometer in an ordinary car, and a microwave or laser radar in a Police car.
No. RADAR stands for RAdio Direction And Ranging. RADAR uses the reflection of pulses of radio waves from objects to measure the direction and range (distance) of the objects from the RADAR unit. Some RADAR units also measure relative speed by measuring the Doppler frequency shift. Chronometers are simply very precise clocks.

mph is a measure of speed, km is a measure of distance. Speed = Distance/Time. You cannot convert distance into speed without knowledge of the time taken for the journey.
Speed. Kilometre measure distance, and hour is a measure of time. Distance / Time = Speed.
in my hands!!!!
By Speed Radar !!
A radar gun measures speed of a moving object basically cops use them
Radar was first used to measure the speed of a moving object in 1935. By 1938, they were used to measure the speed of a fastball thrown by Bob Feller.
Doppler radar
A portable radar unit
You can use a radar gun to measure your break speed. On a simpler level, there is a smartphone app called Break Speed, which does just that.
A Radar gun
Radar is a system that uses radiowaves to measure things like size, distance and speed of a specific object.

The speed is measured by radar from the batsman's end as the ball leaves the bowlers hand.
Using a radar gun similar to one used to measure speed of a baseball being thrown
