Answer:

  1333.3 N

Step-by-step explanation:

The centripetal acceleration is given by ...

  a = v^2/r

  a = (100m/s)^2/(3 m) = (10^4)/3 m/s^2

Then the force on the ball is ...

  F = Ma = (0.4 kg)(10^4)/3 kg·m/s^2 ≈ 1333.3 N

Answer:

<em>y = (x - 4) - 4 </em>

Step-by-step explanation:

m = \frac{y_{2} - y_{1} }{x_{2} -x_{1} }

(- 2, - 10)

(4 , - 4)

m = \frac{-4+10}{4+2} = 1

y + 4 = (x - 4) ⇒ <em>y = (x - 4) - 4</em>

Number 2 please help
Sveta_85 [38]

Answer:

you just have to check the first and the third box

Step-by-step explanation:

put each into slop intercept form

y+6=-5(x-2) is the same as y=-5x+4

y-2=-5(x+6) is the same as y=-5x-28

y=-5x+4

y=-5x-28

all of them have a slope of -5, but you need to plug in (2,-6) to see which on is true
