A falcon dives a distance of 140 metres in 1.6 seconds. Calculate its speed using the formula speed = distance / time. Give your answer to the appropriate number of significant figures.

Jamieson is competing in his school’s 3.0-metre diving competition. For his last dive, he is performing a forward somersault. The duration of the dive must be exactly 1.75 seconds or he will under- or over-rotate before hitting the water. He jumps upwards off the board with a vertical velocity of 6.0 m s−1 and takes $t$t​ seconds to land in the pool. Take the upwards direction as positive.Which of the following correctly describes the initial velocity during the jump?A0 m s−1B6.0 m s−1C−6.0 m s−1D6.0 m s−2

Of all the animals on the planet, the peregrine falcon reaches the highest speeds. It can get to 320 km/h (nearly 90 m/s) in a dive. A particular falcon swoops down to catch a rabbit. It drops vertically from a height of 600 m to 100 m in 10 seconds.Calculate the falcon's average speed, giving units.

While scuba diving, Kendrick rose 8.1meters directly toward the water's surface at a constant velocity. He moved that distance in 1.5minutes, and he was passed by a jackfish swimming south at 15 meters per minute. What was Kendrick's velocity?
