Explanation:
Given
Vertical jump make by the dolphin is given by
Suppose the dolphin jump with an initial velocity of
so u is given by
If dolphin launches at an angle then maximum horizontal range is given by
assuming the of Dolphin to be Projectile so range is given by
substitute the value of
Range will be maximum for
thus
Explanation:
Momentum is conserved:
m₁v₁ = m₂v₂
(42.8 kg + 31.5 kg + 25.9 kg) (19.8 m/s) = (31.5 kg + 25.9 kg) v
v = 34.6 m/s
