Answer:
velocity = 10 m/sec in the same direction as the first body did
Explanation:
The momentum of the body can be calculated as follows:
momentum = mass * velocity
For the first body, we have:
mass = 5 kg
velocity = 2 m/sec
momentum = mass * velocity
momentum = 5 * 2 = 10 kg.m/sec
We know that this momentum is transferred completely to the second body
For the second bode, we have:
momentum = 10 Kg.m/sec
mass = 1 kg
momentum = mass * velocity
10 = 1 * velocity
velocity = 10/1
velocity = 10 m/sec
Finally, we should get the direction of the motion:
Both the velocity of the first and second bodies have positive values. Therefore, the second body is moving in the same direction as the first body did.
Hope this helps :)
Answer:
f(-5) = 5
Step-by-step explanation:
Step 1: Define
f(x) = -x² - 7x - 5
f(-5) is x = -5
Step 2: Substitute and Evaluate
f(-5) = -(-5)² - 7(-5) - 5
f(-5) = -25 + 35 - 5
f(-5) = -25 + 30
f(-5) = 5
2000m/5 would equal 400meters per minute
This is how you find the speed.
WITH THE POWER OF DIVISION!!!
You could also use a normal calculator for this! ;)
