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
Answer:
30
Step-by-step explanation:
If you start at -2F and count all the way to 28F you can mark down every count to get your answer. Or subtract 28F by -2F.
It says Sandeep has twice as much as Sonia. Thus, let Sandeep's amount be 2x and Sonia's amount be x.
Now, together they have 150.
Thus, the equation;
x+2x=150
Now let's solve the equation;
3x=150
x=150/3
x=50
Thus, Sonia has 50
