Question

a diver is attempting a 2 1/2 front dive in a layout position. if the dive is successful, he will rotate 2 1/2 revolutions around his transverse (somersault) axis from takeoff until water entry. the diver's average angular speed during the dive is 5 rev/s, and he is in the air for 0.40 s from takeoff to water entry. is the dive successful?

Answer 1

The dive is successful if the diver completes 2 1/2 revolutions. By using the average angular speed and time in the air, we calculate that the diver completes 2 revolutions, which is the desired outcome for the dive.

Step-by-step explanation:

In order to determine if the dive is successful, we need to calculate the number of revolutions the diver completes during the dive. The average angular speed is given as 5 rev/s, and the time in the air is 0.40 s.

Therefore, the number of revolutions completed would be:

Number of revolutions = Average angular speed x Time in the air

Number of revolutions = 5 rev/s x 0.40 s

= 2 revolutions

The diver completes 2 revolutions, which is the desired outcome for the dive.

Therefore, the dive can be considered successful.
