Trained dolphins are capable of a vertical leap of 7.0 m straight up from the surface of the water - an impressive feat. Suppose you could train a dolphin to launch itself out of the water at this same speed but at an angle. What maximum horizontal range could the dolphin achieve?

14 m

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

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

e) none of the above answers are correct
