Answer:
a)P =14288.4 W
b)P = 19.16 horsepower
Explanation:
Given that
m= 108 kg
Initial velocity ,u= 0 m/s
Final velocity ,v= 19.6 m/s
t= 2.9 s
Lets take acceleration of Cheetah is a m/s²
We know that
v= u + a t
19.6 = 0 + a x 2.9
a= 6.75 m/s²
Now force F
F= m a
F= 108 x 6.75 N
F= 729 N
Now the power P
P = F.v
P = 729 x 19.6 W
P =14288.4 W
We know that
1 W= 0.0013 horsepower
P = 19.16 horsepower
P =14288.4 W
ANSWER:
IV, Type of dish detergent. DV, height of foam. CV, type of container, amount of water in container, temperature of water, time the container is agitated.
Explanation:
Independent variable(IV)- what you change during the experiment.
dependent variable(DV)- what you're measuring during an experiment. The dependent variable is DEPENDENT because it's results DEPEND on the independent variable at play.
Constant variables(CV)- things that do not change in order to isolate the tested variables as much as possible.

Answer:
x = 1.018 m
Explanation:
given,
height of man = 190 cm
= 1.9 m
scale reading on left = 450 N
scale reading on the right = 390 N
Let center of gravity of man be x distance from feet, feet is on right side.
For system to be in equilibrium moment about center should be equal to zero.
∑M = 0
now,
450(1.9 - x ) - 390 × x = 0
450(1.9 - x ) = 390 × x
855 - 450 x = 390 x
840 x = 855
x = 1.018 m
hence, point of center of gravity from feet is equal to x = 1.018 m
