The final velocity of the skateboarder I after the collision is 3 m/s to the left.
<h3>
Velocity of skateboarder I</h3>
The velocity of skateboarder I is determined from the principle of conservation of linear momentum.
m1u1 + m2u2 = m1v1 + m2v2
50(0) + 75(0) = 50v1 + 75(2)
0 = 50v1 + 150
v1 = (-150)/50
v1 = - 3
v1 = 3 m/s to the left
Thus, the final velocity of the skateboarder I after the collision is 3 m/s to the left.

I think it’s b amplitude and wavelength
It is very important to note down all the details that are given in the question. Based on these details the answer can be derived.
Initial velocity of the car (V1) = 0 meters/second
Final velocity of the car (V2) = 40 meters/second
Initial time (T1) = 0 Second
Final time (T2) = 60 seconds (In this case we have converted 1 minute into 60 seconds for the ease of calculation.
Then
Average acceleration = (V2 - V1)/ (T2 - T1) m/s^2
= (40 - 0)/(60 - 0) m/s^2
= 40/60 m/s^2
= 2/3 m/s^2
= 0.67 m/s^2
So the average acceleration of the car is 0.67 meters/second square.

Answer:
Key points that can be found in the realist philosophical position are as follows:
- The view that we observe or identify is real, truly out there.
- The objects which are identified are independent of someone's perceptions, linguistic practices, conceptual scheme, and beliefs.
- Quantum mechanics is an example of philosophical realism that claims world is mind-independent.
