Answer:
Vx = 6 m / s and .vy = 7 m / s
Explanation:
a) Let's substitute the value of time in the equations
x (1) = a +6
y (1) = b + 7
b) and e) We calculate the position for t = 2 s
x (2) = a +12
y (2) = b +14
We calculate the average speed
v = (x (2) -x (1)) / t2- t1
vₓ = ((a + 12) - (a-6)) / (2-1)
vₓ = 6 m / s
= ((b + 14) - (b-7)) / 1
= 7 m / s
c) and f) The instantaneous bone change calculates with the derivative
vₓ = dx / dt
vₓ = 6 m / s
That is constant for all time
= dy / dt
= 7 m / s
d) The speed on the x-axis is constant and is worth vx = 6 m / s
From what we know, we can confirm that this ratio (turning up the volume by one click relative to the TV's overall volume) can be quantified as the Weber fraction.
<h3>What is the Weber fraction?</h3>
This fraction describes the ratio needed for change to a stimulus in which the change is just barely noticeable. This question is a prime example in that it seeks to find out just how low of a difference is needed in TV volume in order for the difference to be noticeable.
Therefore, we can confirm that this ratio (turning up the volume by one click relative to the TV's overall volume) can be quantified as the Weber fraction.

Answer: Accelaration is 2.77 m/s*s
<h2 />
Explanation:
V0=0km/h=0m/s
V1=100 km/h=27.7 m/s
t=10s=
Use equation for accelaration : a=(V1-V0)/t
a=(0m/s-27.7m/s)/10s
a=-27.7s/10s
a=2.77m/s*s
