and whats your point numb nuts.i can't believe you really care about something so pointless,get a life sorry but your a real sorry sounding cu@t .
need to know the speed of the wave at the speed of light 300,000,000 m/s 300,000,000 / 20 = 15,000,000 metres at the speed of sound 333 m/s 333 / 20 = 16.67 metres
Speed = 30 mpsTime = 20sDistance = speed * timeDistance = 30 * 20 = 600 meters.
90 mph
Frequency = (speed)/(wavelength) = 20/2 = 10 Hz
Its initial speed cannot be 20 m, as stated in the question. Secondly, if the initial speed is correctly given, then there is no need to calculate it!
mass*speed squared= momentum 20 kg*8 squared or 64= 1,280 kg-m/s
18 mph
Your average speed is 6.67 mph
3.5 SECONDS
over 20 miles
Fastest about 11 to 13miles per hour
Pandas are no speed demon when it comes to running in a normal manner and are not particularly adept at running backwards.
Donkeys and mules run a little slower than horses. The average speed of a horse gallop is 25 to 30 mph. Wild donkeys run between 20 to 25 mph.
You could stop at 20 miles per hour without hitting him. --------------------- Assuming The Highway Code formula for stopping distances: stopping_distance = thinking distance + stopping time = speed + speed²/20 ft (where speed is in mph) → 65 = speed + speed²/20 → speed² + 20speed + 1300 = 0 → speed = -10 + 10√14 mph ≈ 27.4 mph (The negative square root can be ignored as it gives a negative speed which is nonsense for this problem.) However, this assumes that you observe, think and can start braking within 15/22 (≈ 0.68) seconds of the child running into the road (1ft for every 1 mph of speed), and your braking matches the Highway Code assumptions for good tyres, brakes and dry road conditions.
I am 14 years old. And I can run about 20 mph. But I run every day, the average is about 14 - 16.
Turkeys are not capable of traveling at speeds of 55 mph. The maximum running speed of a turkey is around 20-25 mph.
The momentum of a 20 kilogram dog running at a speed of 8 meters per second is 160 (kg m/s). P=mv P=momentum m=mass v=velocity The units are (kg m/s). P=mv P= 20kg x 8 m/s P= 160 (kg m/s) .
