Answer:
4.36 seconds
Explanation:
According to the question;
- Force is 550 N
- Mass of the car is 1200 kg
- Velocity of the car is 2.0 m/s
We are needed to find the time the car must the tow track pull the car.
- From Newton's second law of motion;
- Impulsive force, F = Mv÷t , where m is the mass, v is the velocity and t is the time.
Rearranging the formula;
t = mv ÷ F
Thus;
Time = (1200 kg × 2.0 m/s²) ÷ 550 N
= 4.36 seconds
Thus, the time needed to pull the car is 4.36 seconds
Given that Tsunami waves are almost the same as ripples since they both caused by throwing a rock into the pond, the major difference between the two is that the energy source of tsunami waves is much greater compared to ripples. Ripples are just transverse waves. Hope this answers your question.

I have put the answer and solution in the files part!
Answer:
An opposing force caused by friction produced a lower acceleration than calculated.
Explanation:
Experimental Evidence.
Scientists conduct experiments or observations to gather evidence that either support or disprove a given hypothesis. Hence, all the scientific explanations are based on this body of observations.
