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.
The average running speed of an AFL player varies depending on the position and fitness level of the player. Generally, AFL players can reach speeds of around 20-30 km/h during a game.
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.
