A 61,000-kg Rocky Mountain Double big rig is traveling at 0.5 m/s.
About what velocity must a 730-kg compact electric vehicle have to
achieve the same amount of momentum as the Rocky Mountain
Double?
Rocky Mountain Double
Small electric car

41.78 m/s

Explanation:

Momentum the defined as the product of mass and velocity of an object hence expressed as p=mv where p represent momentum, m is mass while v is velocity.

The law of conseevation of linear momentum states that the sum of the initial and final momentum should be equal. Therefore, in this case, MV=mu where M and m represent mass of 61, 000 kg and 730 respectively while v and u are their respective velocities.

Making u the subject then

Substituting 0.5 m/s for V, 61000 kg for M and 730 kg for m then the velocity will be

the answer would be   dignified - apex

i'm on my way to history not a mistory.
