Answer:
102.52 W
Explanation:
Power: This ca be defined as the rate at which energy is used up.
The S.I unit of power is Watt(W).
From the question,
P = E/t.............. Equation 1
Where P = average power of the snake head, E = energy of the snake, t = time.
But,
E = 1/2mv²............ Equation 2
Where m = mass of the head, v = velocity of the snake head.
Substitute equation 2 into equation 1
P = 1/2mv²/t ............ Equation 3
Given: m = 170 g = 0.17 kg, v = 28 m/s, t = 0.65 s.
Substitute into equation 3
P = 1/2(0.17)(28²)/0.65
P = 102.52 W.
Hence the average power of the snake = 102.52 W
