Question

A truck driving along a highway road has a large quantity of momentum. If it moves at the same speed but has twice as much mass, what will happen to its momentum? a. zero.b. quadrupled.c. doubled.d. unchanged.

Answer 1

Answer:C

Explanation:

Given

Truck is moving with a large momentum let say P

P is the product of mass and velocity such that if m is the mass and v is the velocity then P is given by

$P=m\times v$

if mass is doubled while v remain same, New momentum is given by

$P'=2m\times v$

$P'=2mv$

Momentum gets doubled  

Answer 2

Answer:

option (c)

Explanation:

Momentum is defined as the product of mass of the object and the velocity of the object.

p = m x v

where, m is the mass of the object and v be the velocity

As the mass is doubled, so that the momentum is also doubled.
