how fast can a greyhound run in mph
Greyhound It is a gentle and intelligent breed whose combination of long, powerful legs, deep chest, flexible spine and slim build allows it to reach average race speeds exceeding 64 kilometres per hour (40 mph).[3][4][5] The Greyhound can reach a full speed of 70 kilometres per hour (43 mph) within 30 metres (98 ft), or six strides from the boxes, traveling at almost 20 metres per second (66 ft/s) for the first 250 metres (820 ft) of a race.[6][7]
Funny Car Horsepower claims vary widely—from 6,978 to 8,897—but are probably around 8,000 HP. Supercharged, nitromethane-fueled motors of this type also have a very high torque, which is estimated at about 7,000 ft⋅lbf (9,500 N⋅m). They routinely achieve a 6G acceleration from a standing start.
Metre per second squared As acceleration, the unit is interpreted physically as change in velocity or speed per time interval, i.e. metre per second per second and is treated as a vector quantity.
Walking Elephants can move both forwards and backwards, but cannot trot, jump, or gallop. They use only two gaits when moving on land, the walk and a faster gait similar to running.[39] In walking, the legs act as pendulums, with the hips and shoulders rising and falling while the foot is planted on the ground. With no "aerial phase", the fast gait does not meet all the criteria of running, although the elephant uses its legs much like other running animals, with the hips and shoulders falling and then rising while the feet are on the ground.[40] Fast-moving elephants appear to 'run' with their front legs, but 'walk' with their hind legs and can reach a top speed of 18 km/h (11 mph).[41] At this speed, most other quadrupeds are well into a gallop, even accounting for leg length.
