By definition,
Momentum = Mass * Velocity
Let v = the velocity of the truck, m/s
The mass of the truck is 36,287 kg.
The momentum is 907,175 (kg-m)/s.
Therefore
907,175 (kg-m)/s = (36287 kg)*(v m/s)
v = 907175/36287 = 25 m/s
Answer: 25 m/s

Answer:
Nature and size of image:
the image is formed at the focus (F), the image is virtual,erect and highly diminished.
P1 and P2 are the pressures, and V1 and V2 are the volumes. So you take the first pressure and volume you are given and place them into the equation P1V1 so the first part of the equation would be 101000*0.5 = P2V2. You then rearrange the equation to find what you want, in this instance you would do 50500/0.25 = P2... therefore P2 = 2020000Pa or 2.02*10^6Pa
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.
