What is collision
?</h3>
The collision is an encounter between particles resulting in exchange or transformation of energy.
According to the question,
Force,
F = 5 N
Mass,
m = 3 kg
Velocity,
v₁ = 9 m/s and v₂ = 3 m/s
As we know,
F=m*(v/t)
so,
5=3*(9-3/t)
T=3*6/5
T=18/5
hence, the time for the collision is
T= 3.6S.

Answer: {y∈R: y≤6} or [6,∞)
Explanation:
This problem doesn't require too much math. If you look at the equation given, you can see that it is a quadratic equation in the form of
. Since this is a quadratic equation, we have an idea of that the graph would look like. It either curves up or down. Since this is a positive equation, 
, we know that this is going to curve up. In order to find the minimum of the curve, you would use 
.
This means the x value of the parabola is -2. To find the y, you plug -2 into the original equation.
Now that we know the y value of the minimum/vertex is 6, and it is determined that the parabola curves up, the range is y≤6 because the range starts at 6 and goes off toward infinity.
