Ameteorite of mass 1500kg moves with a speed of 0.700c . find the magnitude of its momentum p. express your answer in kilograms times meters per second to three significant figures.

Explanation:

The relativistic momentum of an object is given by

where:

is the relativistic factor, with v being the speed and c being the speed of light

m0 is the rest mass of the object

v is the speed

In this problem, we have

m = 1500 kg is the rest mass

v = 0.700 c is the speed of the meteorite

So we find

And so the momentum is

grav potential energy

f=ma newton

f=100x2.5=250n
