Limbs: Cetacean flippers have the same bones as the forelimbs of other mammals. The humerus, radius, ulna, carpals, metacarpals and phalanges are all present. However, in cetaceans the radius and ulna (forearm) and humerus (upper arm) are fused.
Hope this helps! :D
Answer:
Speed. I am speed.
Explanation:
The FitnessGram Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. A single lap should be completed each time you hear this sound. Remember to run in a straight line, and run as long as possible.
Answer:
Vf = 22.62 [m/s] in 2 seconds.
Explanation:
In order to solve this problem we must use the following kinematics equation
where:
Vf = final velocity [m/s]
Vi = initial velocity = 3 [m/s]
g = gravity acceleration = 9.81 [m/s^2]
t = time = 2 [s]
Vf = 3 + (9.81*2)
Vf = 22.62 [m/s]
