The maximum speed of Tim is 16.95 m/s.
The given parameters:
- Mass of the rope, m = 71 kg
- Tension on the rope, T = 220 N
- Coefficient of kinetic friction, = 0.1
- Time of motion, t = 8 s
<h3>What is Newton's second law of motion?</h3>
- Newton's second law of motion states that, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
The net force on Tim is calculated by applying Newton's second law of motion as follows;
Thus, the maximum speed of Tim is 16.95 m/s.

The answer is A. the same.
Since the container is sealed, their will be no loss of material from the container which means that the mass won’t vary.
The image shows a continuous signal and is not made of numbers, so this signal is an analog signal. Gina is not correct in her identification of the signal.
<em><u>D. acceleration Hope this helps!</u></em>
1/2*2.8*x^{2}=2.8*9.81*1.50
X=5.425
Because K.E=1/2*M*V² and it is equal to P.E in the conservation of energy which means its K.E=P.E
P.E=m*g*h
So K.E equals 1/2*2.8*(5.425)²=41.20
