Answer: Sam provides the biggest power
Explanation: <u>Power</u> is defined, in Physics, as the rate of work done. <u>Work</u> is energy transferred to an object due to the force causing the displacement of the object.
So, to determine Power:
For Sam:
P =
P = 50 Watts
The unit for Power is [P] = J/s = Watt
For Gary:
P =
P = 40 Watts
Comparing power of Sam and Gary, we can conclude that Sam provides the biggest power of 50 Watts.
<h2>Answer:</h2>
<em><u>(a). v = 7.745 m/s</u></em>
<em><u>(b). a = -1500 m²/s</u></em>
<h2>Explanation:</h2>In the question,
(a).
We know that the height of the squirrel from the ground, h = 3 m
Now,
From the equation of the motion we can say that,
Also,
<em><u>Therefore, the velocity of squirrel before hitting the ground is 7.745 m/s.</u></em>
(b).
The squirrel stops in the distance of 2 cm after falling through the height.
So,
The deceleration of the squirrel is = a
So, using the law of the motion in the last 2 cm of distance travelled.
Where,
u = 7.745 m/s
So,
<em><u>Therefore, the deceleration of the squirrel is given by, a = -1500 m²/s</u></em>
