Tap water isn't pure. it just isn't H₂O.
Answer:879.29 N-m
Explanation:
Given
mass of first child 
distance of first child from tree is 
tree is inclined at an angle of 
mass of second child 
distance of second child from tree is 
Weight of first child
Weight of second child
Torque of first child weight
Torque of second child weight
Net torque 
This item is solved through the concept of the conservation of momentum which states that the momentum before and after collision should be equal.
momentum = mass x velocity
(1,600 kg)(16 m/s) + (1.0x10^3 kg)(10 m/s) = (1600 + 1000 kg)(x)
The value of x is 13.69 m/s. Thus, their final speed is approximately letter D. 14 m/s.
When scientists work together it helps them achieve their goals when they share different ideas with eachother
Use w=m*g value of g is 1.67m/s^2
