What velocity in km/hr would it take to accelerate a 2 kg object to the same momentum of a 1500 kg object with a velocity of 1.62 m/s

4374 km/h

Explanation:

The momentum of the 1500 kg object is given by:

where

m = 1500 kg is the mass

v = 1.62 m/s is the velocity

Substituting,

We know that the smaller object of mass m' = 2 kg has the same momentum, so we can find its velocity by re-arranging the same equation:

Now to convert into km/h, keep in mind that:

1 km = 1000 m

1 h = 3600 s

So, we find

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
