The coefficient of kinetic friction between the block and the incline is 0.168.
<h3>
Coefficient of kinetic friction</h3>
The coefficient of kinetic friction is determined from the principle of conservation of energy as follows;
distance traveled on the incline = L
L = h/sin35
L = 1.743 h
Since it takes twice the time travel down,
velocity to slide = 1.743 h/2t = 0.871 v
- v is the velocity to drop from the vertical height
K.E of the block when it slides = ¹/₂mv₁² = ¹/₂m(0.871v)² = 0.871²(K.E to fall) = 0.758K.E to fall straight down
<h3>Energy lost to friction</h3>
1 - 0.758 = 0.24
<h3>Conservation of energy</h3>
μmgcos(35) = 0.24(mgsin(35)
μcos(35) = 0.24(sin(35)
μ = 0.168

Answer:
5.67 x 10^ 1
Explanation:
Move the decimal once to the left
Answer:
C) Rear
Explanation:
For better understanding, let me explain first what actually is the Whiplash injury. It usually occurs in the accidents related to vehicles and cause injury in the neck. It happens because of the very forceful, rapid movement of head and neck forward and backward. So unfortunately if there is a sudden impact of car from the rear and if it's velocity changes from 10 to 15 km/h (as the studies show) it will results in the whiplash injuries. So the correct option here is the third one "<em>rear</em>".
<span>If you have only two
data from two recording stations then you will be having a hard time finding
the correct location of the epicenter. This is because triangulation method requires
3 recording station. If you have 2 recording station, the 2 circles will
intersect at 2 points giving you 2 locations that could possibly be the
epicenter.</span>
