A car is traveling on a straight, level road under wintry conditions. Seeing a patch of ice ahead of her, the driver of the car

slams on her brakes and skids on dry pavement for 50 m , decelerating at 7.5 m/s2 . Then she hits the icy patch and skids another 70 m before coming to rest.
A) If her initial speed was 78 mi/h , what was the magnitude of the deceleration on the ice?

A 60kg block is at rest on a ramp inclined at 35 degrees.
weeeeeb [17]

Answer:

Explanation:

(a)Gravitational Force is W=mg

Frictional force is f

Normal force is N

(b)Since the block is in Equilibrium therefore from diagram we can see that  

f=mg\sin \theta

f=60\times 9.8\times \sin 35

f=337.26 N

(c)Magnitude of Normal Force

N=mg\cos \theta =481.66 N

(d)friction is also given by

f=\mu mg\cos \theta

and f=mg\sin \theta

thus tan \theta =\mu

\mu =0.7

Help with 5 and the question below. BRAINLIEST FOR THE CORRECT ANSWER! Urgent Physics help!
krok68 [10]

Sound level at distance of 15 m is given as 20 dB

so intensity at this distance is given as

L = 10 Log\frac{I}{I_0}

20 = 10 Log{I}{10^{-12}}

I_1 = 10^{-10}W/m^2

now if we move closer to some some distance the sound level is now 50 dB

now the intensity is given as

L = 10 Log\frac{I}{I_0}

50 = 10Log\frac{I}{10^{-12}}

I_2 = 10^{-7}W/m^2

now we know that

\frac{I_1}{I_2} = \frac{r_2^2}{r_1^2}

\frac{10^{-10}}{10^{-7}} = \frac{r_2^2}{15^2}

r_2 = 47 cm

so now the distance from friend must be 47 cm
