A small ball of mass m,-0.84kg and initial speed v,-18.2m/s makes a collision with another ball of mass m, -1.4kg which is initially at rest on a frictionless horizontal table. After the collision the balls move as shown in the figure. Given 8-24°, determine the speed of m; just after the collision, that is, v;-? Express you answer using one decimal place.

it is the second option.

the awnser is d you right bro                      

if i am correct, your answer choices are:

a. the temperature remains constant

b. the temperature increases at a constant rate

c. heat flows at a constant rate into the system

d. heat flows at a constant rate out of the system

e. no heat flows into or out of the system

if so, then the answer is e. no heat flows into or out of the system.
