Vertical stretch by a factor of 3 and a reflection over x-axis is g(x)= -3|x|
If using the radius, you would multiply the radius by 2*pi, to calculate the circumference, which should be the same as the answer i got.
Step-by-step explanation:
When the car stops, the speed is zero.
When S = 0, -10t + 45 = 0, t = 4.5.
Hence it will take 4.5 seconds for the car to stop.
Answer: ΔKE = 760.5 Joules
Step-by-step explanation:
Isnt the formula for ΔKE = 0.5m*v^2???
Im not going to use that formula you gave me, its wrong.
900/2 = 450
1.3^2 = 1.69
450 x 1.69 = 760.5 Jules
This is also the wrong subject btw
For a;

For b;

If my calculations are incorrect, then sorry ;/
