Answer: In that case, Put something like "My hypothesis is that the car will take (x) seconds to get to checkpoint 1, (x) seconds to get to checkpoint 2, (x) seconds to get to checkpoint 3, and (x) seconds to get to checkpoint 4" Replacing x with random numbers, or number close to the actual found numbers, but honestly as long as the guesses arent outrageous you should get the question right

Answer:

My hypothesis is that the car will take (x) seconds to get to checkpoint 1, (x) seconds to get to checkpoint 2, (x) seconds to get to checkpoint 3, and (x) seconds to get to checkpoint 4.

This above is a good starter the hypothesis.

Explanation:

I am literally here struggling to write a lab report because I didn't pay any attention while doing this lab project.

I didn't even record the seconds it took for the race cars to get to each checkpoint. ;; very d u m b move, correct, I know it was. I really regret it now. I never knew we had to write a whole lab report for it.

Pregunta completa:

Un barco va a una velocidad de 45 ml/h, luego el capitán ordena acelerar hasta que la velocidad hasta que la velocidad sea de 60 mll/h. si la operación dura 30 minutos.

A cual fue la aceleracion?

B qué distancia recorre?

Responder:

30 millas / hora

26.25 mi

Explicación:

Dado que :

Velocidad inicial, u = 45 mi / hr

Velocidad final, v = 60 mi / hr

Tiempo, t = 30 minutos = 30/60 = 0,5 h

Aceleración, a = cambio de velocidad con el tiempo;

a = (v - u) / t
