true or false:acceleration toward the center of a curved or circular path is called gravitational acceleration.
nalin [4]
Nope. It's called 'centripetal' acceleration. The force that created it MAY be gravitational, but it doesn't have to be. For things on the surface of the Earth moving in circles, it's never gravity.

Alex787 [66]

The final momentum of the system would be 6680 Kg m/s

<h3>What is momentum?</h3>

It can be defined as the product of the mass and the speed of the particle, it represents the combined effect of mass and the speed of any particle, and the momentum of any particle is expressed in Kg m/s unit.

Mathematically the formula of the momentum is

P = mv

Two cars are driving toward each other in a straight line. Car A is 1400 kg and driving at 11 m/s. Car B is 1090 kg and driving at 8 m/s. If the two cars collide inelastically, As we know that the momentum of a system is conserved during the collision

initial momentum = final momentum

the initial momentum of the system = 1400 ×11 + 1090×(-8)

                                                           = 6680 Kg m/s

The final momentum of the system =  6680 Kg m/s

Thus,The final momentum of the system would be 6680 Kg m/s
