The velocity of B after elastic collision is 3.45m/s
This type of collision is an elastic collision and we can use a formula to solve this problem.
<h3>Elastic Collision</h3>

The data given are;
- m1 = 281kg
- u1 = 2.82m/s
- m2 = 209kg
- u2 = -1.72m/s
- v1 = ?
Let's substitute the values into the equation.

From the calculation above, the final velocity of the car B after elastic collision is 3.45m/s.

Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. ... In reaction, a thrusting force is produced in the opposite direction.

Answer:
and
. The missing ion would be
.
Explanation:
In a double replacement reaction, two ionic compounds exchange their ions to produce two different ionic compounds.
In this question, the two ionic compounds are:
, and
.
In particular,
is made up of
ions and
ions, while
is made up of
ions and
ions.
In a binary ionic compound, cations (positive ions) can only bond to anions (negative ions.)
is a cation. In
,
was bounded
anions. During the reaction, it bonds with
anions to produce
.
is also a cation. In
,
was bounded to
ions. During the reaction, it bonds with
anions to produce
.
Hence, the two products will be
and
.
Note that charges on the ions must balance. For example, a
ion carries twice as much charge as an
ion. As a result, each
ion would bond with twice as many
ions as
would in
.
It would go to the positive charge im like 99% sure of that
