Answer:
given values are:
- u=20 m/s
- t= 30 s
- s= 1200 m
- v= ?
- a=?
<h2>s = ut + 1/2 at²</h2>
1200 = 20×30 + 1/2 × 30²a
1200= 600 + 1/2 × 900a
600 = 450a
a = 600 / 450
a = 1.33 m/s²
<h2>v²= u² +2as</h2>
v² = 20² +2 × 1.33 × 1200
v²= 400 + 3192
v = √3592
v = 59.9 ≈ 60 m/s
The answer is 9.6 repeating so the two numbers that my answer lies in are 9 and 10.
Y=-1/2x+3 is the slope intercept form.
-28x-49x-16+32x
-77x-16+32x
-45x-16
