Answer:
Step-by-step explanation:
Let v be the speed after the collision of both the cars.
Now, momentum is given by: mass × velocity, then by equating the total momentum before and after the collision of the two cars, we get
⇒
⇒
⇒
Thus, they are moving at the velocity of
<span>The volume of the cylinder will be 2</span>π
As shown in figure, R is the base radius of the cylinder.
H is the height of the cylinder.
Given: H = diameter of the base of cylinder.
Now, diameter of the base = 2R
So, H = 2R
<span>Volume of cylinder = π×</span>×H
<span> = π×</span>×(2R)
<span> = 2 π </span> cubic units.
