<u>Given</u><u>:</u>
- mass of cat ( m ) = 10 kg
- Acceleration ( a ) = 10 m/s²
<u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u><u> </u>
If it runs into a wall what force will be exerted by the cat?
<u>Formula</u><u> </u><u>used</u><u>:</u>
Force = mass × acceleration
<u>Solution</u><u>:</u>
Force = mass × acceleration
Now, Putting these values of m and a in the above equation.
we get:
F = 10 × 10
= 100 N
Thus, the force will be exerted by the cat is 100 N.
Answer: k = {8, -8}
<u>Step-by-step explanation:</u>
In order for a quadratic equation to have exactly one solution, the discriminant must equal zero. → b² - 4ac = 0
4x² + kx + 4 = 0
↓ ↓ ↓
a=4 b=k c=4
b² - 4ac = 0
k² - 4(4)(4) = 0
k² = 64
k = √64
k = ± 8
