A truck has a velocity of 25 m/s and a momentum of 25.000 kg*m/s. What is its
mass?

1000kg

Explanation:

We can use the equation "p=mv"

If we rearrange the equation to find mass (m), then the equation becomes:

m=p/v

We can substitute in the values of p and v as they are already given in the question.

So, now we just substitute in the values to get our answer.

m=p/v

m=25,000/25

m=1000kg

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
