You are driving at the speed of 33.4 m/s (74.7296 mph) when suddenly the car in front of you (previously traveling at the same s
romanna [79]

Answer:

Part a)

a = - 8.45 m/s/s

Part b)

d = 66 m

Part c)

d = 14.16 m

Explanation:

Part a)

when car apply brakes then the friction force on the car in front of us is given as

F_f = \mu mg

here we need to find deceleration due to friction

a = \frac{F_f}{m}

a = -\mu g

a = -8.45 m/s^2

Part b)

Braking distance of the car is the distance that it move till it stops

so we will have

v_f^2 - v_i^2 = 2ad

0 - 33.4^2 = 2(-8.45)d

d = 66 m

Part c)

Since we know that average reaction time for human is 0.424 s

now we know that during reaction time our car will travel at uniform speed

so we will have

d = vt

d = (33.4) (0.424)

d = 14.16 m

Who came up with the theory of relativity?
liberstina [14]

Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels
