When things are completely inelasric, can they move togther and coalesce?

Answer 1

YES THEY CAN, it is a possibility don’t lack

Question 2

For collisons , remember to check the DIRECTIOM OF YOUR ARROW

Answer 2

Always at the start of the q state which side is positive (bevause might be better to change it based on q)

And then adjust the velocities accordingly

Question 3

How to show one ball will catch up with other?

Exam scheme method ?

Answer 3

If v of the ball > than other it will catch up

Thus you can SUBTRAVT them and show that the final answer is GREWTER THAN 1

Question 4

Directions matter fir calcuskting ke?

Answer 4

No they DONT BECAUSE THRY JUST GET SQAURED

Question 5

When a ball collided with a wall, what’s the only direction it can go and hence what should your awwow be

Answer 5

BACKWARDS

So the velocity you calculate = the velocity backwards

Question 6

What should you use to find VELOCOTY of ball when it collided with wall and why not the other

Answer 6

Have to use restriction, can’t use momentum because we don’t know momentum of wall, and so can’t form equations
