2) A 1.5 kg cart and a 1 kg cart are sitting next to each other. The plunger of the 1.5 kg cart extends and pushes the carts apart. The 1 kg cart has a velocity of 2 m/s to
the right. What is the velocity of the 1.5 kg cart?

Because its reliable.   there is no pollution  the chances of a radiation leak is low

Two cars collide, lock bumpers and move together after the collision.this collision is known as perfectly inelastic collision.

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
