Step-by-step explanation:
You can try to use the internet for the answer to some of those questions.
Answer:
The answer is 1 13/27.
Step-by-step explanation:
First, convert any mixed numbers to fractions --
the initial equations then reads as 5/3 x 8/9.
Then, applying the fractions formula for multiplication --
5 x 8 / 3 x 9
40/27
Simplifying the above --
1 13/27
Answer:
They traveling at
in backward direction.
Step-by-step explanation:
Given mass of Ammy 
and velocity is forward at 
Also, mass of Jenny 
Who is travelling in opposite direction 
Let velocity in forward direction is positive and velocity in backward direction is negative.
Also, velocity after crash is 
As they crashed into each other and they moved as one mass. We can apply principle of conservation of momentum.
Conservation of momentum says momentum before collision should equal to momentum after collision.


So, velocity after collision
≅
is in opposite direction. That is the direction of Jenny.
