Step-by-step explanation:
The law of conversation tells us that energy can't be created or destroyed. So, the total energy of an isolated system should be constant.
This also works for momentum. When 2 objects collide, their total momentum will not change. Some of the energy can be transferred which change the momentum of individual object, but not the sum/total.
19.2
To find the hypotenuse the equation would be: a^2 + b^2 = c^2.
12 squared is 144 and 15 squared is 225. Add them and you get 369. Then, square root 369 to isolate c. It'd be about 19.2
Answer:
Step-by-step explanation:
b increased by 16 is at most 20 in equation form
increased means add
b+16
is at most means
