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?

Question 1
During a rugby game two players are running toward each other.
One has a mass of 83.9 kg and the other has a mass of 59.9 kg. The
player who has the bigger mass is running at 1.90 m/s and the other
is running at 4.70 m/s. They hit each other, fall to the ground and
slide while attached to each other. If the coefficient of kinetic
friction between the players and the ground is 0.300, how far...

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...
