Answer:
4.53482 m/s
4.506 m/s
Explanation:
= Mass of player = 75 kg
= Initial velocity of player = 4.6 m/s
= Mass of ball = 0.47 kg
= Initial velocity of ball = 15 m/s
The linear momentum of the system is conserved
The player's speed is 4.53482 m/s
In the second case the equation of momentum is
The player's speed is 4.506 m/s
It is currently organised by the increasing atomic # based on the actual nuclear charge of the elements
Answer:
A procedure according to the norms.
Explanation:
If possible, proceed to fix the leak in no more than 30 days from the moment it was discovered.
Otherwise, during the first 30 days develop a planification to backfit the leak or, if needed, retire the appliance. This should be executed within one year.
Answer:
285.7s
Explanation:
Given parameters:
Speed of the person = 1.4m/s
Unknown:
Time it takes to walk one time round the track = ?
Solution:
The circumference of the track is 400m for a standard pitch.
Now;
Speed = 
Time = 
Now insert the parameters;
Time = 
= 285.7s
44,512,992 mm/m. Hopefully...
