What is the net force on a Mercedes convertible traveling along a straight road at a steady speed of 100 km/h?

luda_lava [24]

Answer:

5) 0 N

Step-by-step explanation:

According to Newton's second law of motion: "The acceleration of an object produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force and inversely proportional to the object's mass" .

Because the vehicle travels at a constant speed, its acceleration at zero, so

$A=F_{net}/m$ ,

$F_{net}=A*m; A=0\\F_{net}=0$

Suppose Clay, a grocery store owner, is monitoring the rate at which customers enter his store. After watching customers enter f

Kitty [74]

Answer:

70th percentile for the amount of time between customers entering is 30.10

Step-by-step explanation:

given data

mean = 25

to find out

What is the 70th percentile for the amount of time between customers entering Clay's store

solution

we know that here mean is

mean = $\frac{1}{\lambda}$ ..................1

so here 25 = $\frac{1}{\lambda}$

and we consider time value corresponding to 70th percentile = x

so we can say

P(X < x) = 1 - $e^{- \lambda *x}$

P(X < x) = 70 %

1 - $e^{\frac{-x}{25}}$ = 70 %

1 - $e^{\frac{-x}{25} }$ = 0.70

$e^{\frac{- x}{25} }$ = 0.30

take ln both side

$\frac{-x}{25}$ = ln 0.30

$\frac{x}{25}$ = 1.203973

x = 30.10

70th percentile for the amount of time between customers entering is 30.10
