Newton's first law is "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
Basically it means an object won't move unless something moves it, and an object won't stop moving unless something stops it.
2.Improving my balance and coordination can affect my performance in sports or recreational activities by planing better in activities also <span>improving my speed. My activities all need skills that I am really good at.
3.</span>The activity that was most difficult for me to perform was the Stork Stance test because I am not good with balancing and that is something <span>I need to improve.
4.</span>An activity that could help improve my striking and my reaction time.
5.One sport that I have never done but that I would like to try one day is <span>baseball.
</span>One element of skill-related fitness that is important to being successful in the activity is speed and reaction time skills.6. R<span>unning, jogging, sprinting, and jump roping.</span>

Explanation:
Answer:
41.74 m/s
Explanation:
The energy used to draw the bowstring = the kinetic energy of the arrow.
Fd = 1/2mv²................................ Equation 1
Where F = force, d = distance move string, m = mass of the arrow, v = speed of the arrow.
make v the subject of the equation
v = √(2Fd/m)...................... Equation 2
Given: F = 201 N, m = 0.3 kg, d = 1.3 m.
Substitute into equation 2
v = √(2×201×1.3/0.3)
v = √(1742)
v = 41.74 m/s.
Hence the arrow leave the bow with a speed of 41.74 m/s
