Explanation:
(10) Mass of a soccer player, m = 0.42 kg
Initial speed, u = 0
Final speed, v = 32.5 m/s
Time, t = 0.21 s
We need to find the force that sends soccer ball towards the goal.
Force, F = ma

So, 65 N of force soccer ball sends towards the goal.
(11) Mass of the satellite, m = 72,000 kg
Initial speed, u = 0 m/s
Final speed, v = 0.63 m/s
Time, t = 1296 s
We need to find the force is exerted by the rocket on the satellite.
Force, F = ma

So, 35 N of the force is exerted by the rocket on the satellite.
Hence, this is the required solution.
Answer:
Is to add all forces, for example either the gf = gravitational force
Ff= force fiction
Fn= normal force
Thus, fg + ff + fn = y will give you results
Well then the forces you use in your exercises or questions.
The gravitational force acting upon the woman is equal to <u>-588.6N</u>
Why?
To solve the problem, we need to consider that two forces are acting upon the woman, the first one is related to her weight and the second one is related to the acceleration of the elevator.
Gravitational force acting upon the woman:

Hence, we have that the gravitational force acting upon the woman is equal to -588.6N.
Have a nice day!
