Answer:
0.15N
Step-by-step explanation:
Given data
Mass= 0.0056kg
distance= 4.85m
Velocity= 11.4m/s
The expression for the force is
F= mv^2/r
substitute
F= 0.0056* 11.4^2/4.85
F= 0.0056*129.96/4.85
F= 0.727776/4.85
F= 0.15N
Hence the force is 0.15N
Answer:
option #4 (-oo, +oo)
Step-by-step explanation:
_______
The example of exponential growth is: <span>c. y=0.5(1.5)x </span>
The function y = ab˟ is a can only be growth function if the value b>1. And if 0<b<1 it will decay. Therefore, the only correct value that fits the definition of exponential growth is option C.
Answer:
The average acceleration of train is 
Step-by-step explanation:
We have,
A train that slows down from 15 m/s to 8.6 m/s in 1.2 s. It means that 15 m/s is its initial velocity and 8.6 m/s is its final velocity.
It is required to find the average acceleration of the train.
The average acceleration of train is . Negative signs shows that the train is decelerating.
Answer:y=9.5x-0.5
Step-by-step explanation:
Ok, so you need to use the equation y2-y1/x2-x1 to find the slope. So (18.5-4.25)/(2-0.5) so 14.25/1.5 , calculate that and you get 9.5 which is your slope, apply that to the slope formula which is y=mx+b where (m) is slope and (b) is y intercept and you get y=9.5x-0.5
