Answer:
The maximum acceleration experienced by the sprinter is and it is experienced in the first phase when the sprinter starts his sprint.
Explanation:
Since the sprinter attains a final speed of 34 km/h in runing 200 meters while starting from rest we have
Using the third equation of kinematics we have
where
v is the final speed
u is the initial speed
a is the acceleration
s is the distance covered
Since it is given that sprinter starts from rest thus u= 0 m/s and v= 34 km/h = 9.4m/s this speed is attained at s = 78 m
Applying values in the above equation we get
Since after that the sprinter moves at a constant velocity thus in that phase it's acceleration is
Now since the sprinter decelerates to 30 km/h or 8.33 m/s in final 63 meters thus the deceleration experienced is again found by third equation of kinematics as
Upon comparing the maximum acceleration experienced by the sprinter is
Answer:
$958.25
Explanation:
PV = FV(1 +r)^(-t) . . . . present value of an amount earning rate r compounded annually for t years
PV = $3000(1.08^-5) ≈ $2041.75
The equivalent present value is $2041.75.
__
This amount is less than the offered amount by ...
$3000 -2041.75 = $958.25
She should pay you $958.25 less in order to make the offers equivalent.

Density is the mass per unit volume, it is usually measured in kg/m³.
The density of a crystal structure is given by:
Answer:
62.5%
Explanation:
We are given that
A ten-station transfer machine has ideal cycle time=30 sec=
Frequency of line=0.075 stops per cycle
Average time=4 min
We have to determine the line efficiency
Line efficiency=62.5%
Hence, the line efficiency=62.5%
Answer:
OSHA states the pedestrian has the right of way; therefore, operators must be on constant alert. The forklift operator is required to slow down and sound their horn at doorways, intersections, blind spots and when entering or exiting a building.
