Answer:
Force is 57.69 N to the opposite direction of motion of dolphin.
Explanation:
We have force is the product of mass and acceleration.
That is
Force = Mass x Acceleration
F = ma
Mass of dolphin, m = 30 kg
We have equation of motion, v = u + at
Final velocity, v = 7 m/s
Initial velocity, u = 12 m/s
Time, t = 2.60 s
Substituting
7 = 12 + a x 2.6
a = -1.92 m/s²
Force, F = 30 x -1.92 = -57.69 N
So the force is 57.69 N to the opposite direction of motion of dolphin.
She misses. She should have accelerated faster in order to get to her target.
I don't understand this question
<em>answer:</em>
From the fan side: Salary caps mean better competition and more parity between all teams in a given league (in theory, anyway). Salary caps in the NFL, NBA and NHL can foster this, but in MLB, luxury tax requirements may not be enough to prevent large-market teams from dominating.
