Answer:
x = -6.5 meters
Explanation:
The position of a ball as a function of time t is given by :
..................(1)
Where t is time in seconds
We need to find the position of the ball at 1.9 s. It can be simply calculated putting t = 1.9 s in equation (1) as :
x = -6.5 meters
So, the position of the ball at 1.9 seconds is -6.5 meters. Hence, this is the required solution.
I think it would be helpful to measure gravity so we know how it affects animals and plants and planes and spaceships and cars. I think the most important type of information it gives us is just like making sure people are safe and that there’s nothing we are going on or that the gravity increases at a rate or if it decreases just so we know how to handle it in the future and I think that information would be useful so we don’t die.
Answer:
The toy car
Explanation:
the real car is parked so yeah but maybe in some way technically the real car has more "momentum"
The formula relating frequency and period of a wave is simply frequency = 1 / time. Therefore, by rearranging we also see that time = 1 / frequency. The period of a 440 Hertz sound wave is 1 / 440 seconds. The speed of the wave can also be determined very simply using the formula speed = wavelength x frequency.
