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:
72
Step-by-step explanation:
1 out of 10 do not recommend naps, so 9 times as many do recommend naps.
9 × (8 doctors) = 72 doctors . . . . . recommend naps
The geometric mean is different than algebraic mean - algebraic is adding up all the numbers and dividing it by the number of numbers, but geometric is multiplying them and getting the root of the product of all the numbers. For example, if there were 10 numbers, we would have the 10th root of the product of all the numbers or the product to the power of 1/10.
Since there are 2 numbers, we simply have the square root -
due to that 2²=4, so we can divide what is in the square root by that and take the 2 out.
