The car can't end up moving faster than the truck. Momentum doesn't affect speed, it only affects whether the truck can move the car. Since the truck weighs more, the car will be moved. If the truck is moving at 20 MPH, the car will start moving at 20 MPH on impact, but unless the truck continues moving and speeds up, the car won't move any faster than the original 20 MPH of the truck.
1 unit.
A speeding missile, or any moving object, has momentum. Force was used to cause it to move in the first place. If this object strikes another object, it will then exert a force on the object that it strikes.
The product of mass and velocity determines the momentum of a moving body.
Momentum = mass x velocity. You already stated the mass and velocity so you can figure out the momentum.
If you return to the same state of motion before you began gaining momentum, then momentum lost will be equal to momentum gained. I mean really, if you start out not moving with a momentum of 0 and end not moving with a momentum of 0, then of course there the bloody same. If you start at 0 and never stop moving, then obviously your not losing momentum so the statement is false.
no
You need to frame your question better. A movinng object will not change momentum unless a force acts upon it. A force could be supplied by many things including a collision, gravity, friction What evr happens, energy will be conserved. If friction through air reduces a body's momentum, then the momentum of the of the body will be transfered to momentum of the air particles (which is ultimately seen as heat, and is infact an increase in speed and hence momentum of the molecules

Momentum is motion. When a car is moving it is exhibiting momentum. A young professional getting promotions is experiencing momentum.
The Roller-skate Momentum = (mass) multiplied by (speed) . Anything moving has more momentum than anything that's not moving. The thing that's not moving has zero speed, so it also has zero momentum.
Any moving object with mass has momentum, since p = mv, where p is momentum, m is mass, and v is velocity.
