TWO SEPERATE QUESTIONS, thank you question 1. Soccer player one has a mass of 45 kg...
question 1. Soccer player one has a mass of 45 kg and moves it
to the right with a speed of 1.4 m/s. Soccer player two has a mass
of 32 kg and moves to the left with a speed of 2.1 m/s.
What is the magnitude of the total momentum of the two
players?
question 2. A young hockey player stands at rest on the ice
holding a 1.1-kg helmet. The player tosses the helmet directly in
front of him with a speed of 7.0 m/s and recoils with a speed of
0.25 m/s.
what is the mass of the hockey player?

Can you solve it please
Question 1:
A. A m1 = 80 kg ice skater moving at 50.4 km/h due North crashes
into a stationary skater of equal mass. After the collision, the
two skaters move as one body at 6 m/s due North. If the collision
lasts for 2.0 milliseconds, use the impulse – momentum theorem to
find: i. The impulse delivered to the m1 skater due to the
collision. ii. The magnitude of the average force exerted
on...
