Sometimes a new experimental result may seem to go against a well-established scientific theory. Which statement BEST describes
MrMuchimi
The best thing to do in this case is to redo the experiment and re record the info, it has to be precise and accurate so you also have to check if your procedure is correct. If the results are both accurate and precise then you have to report your findings to the committee of that specific field. <span />

Durante un intento juego de croquet, una bola de 0.52 kg en reposo sobre el cesped es golpeada por un mazo con una fuerza promed
Romashka [77]

Answer: 2.63 m/s

Explanation:

The question in english is written below:

During an attemp of croquet game, a 0.52 kg ball at rest on the grass is hit by a mallet with an average force of 190 N, if the mallet is in contact with the ball for 7.2(10)^{-3} s,  Whay is the speed of the ball just after being hit?

According to Newton's second law of motion, the force F exerted on an object is directly proportional to its mass m and acceleration a:

F=m.a (1)

On the other hand, acceleration is defined as the variation of velocity V in time t:

a=\frac{V}{t} (2)

Substituting (2) in (1):

F=m\frac{V}{t} (3)

Where:

F=190 N

m=0.52 kg

t=7.2(10)^{-3} s

Isolating the velocity V from (3):

V=\frac{Ft}{m} (4)

V=\frac{(190 N)(7.2(10)^{-3} s)}{0.52 kg}

Finally:

V=2.63 m/s
