Answer:
s=1/2at²+v(initial)t
s=1/2(3)(30)²+(0)(30)
s=1/2(3)(30)²+0
s=900(1/2)(3)
s=450(3)
s=1350m

Answer:
(a) Velocity will be 17.146 m/sec
(b) Volume flow rate will be
Explanation:
We have given height of the dam h = 15 m
Acceleration due to gravity
Effective area
(a) From conservation of energy
Potential energy at the top will be equal to kinetic energy at the bottom
So
(b) We have to find the volume flow rate
Volume flow rate is given by
The sum of the initial and final velocity is divided by 2 to find the average. The average velocity calculator uses the formula that shows the average velocity (v) equals the sum of the final velocity (v) and the initial velocity (u), divided by 2.
Answer:
For C is B and for D is A
Explanation:
B because that's where the b car will do all the force to go up, and A because there the car doesn't have to do any force other than the natural, and it already brings that on it's own.
Answer:
12.6332454263 m/s
Explanation:
m = Mass of car
v = Velocity of the car
= Coefficient of static friction = 0.638
g = Acceleration due to gravity = 9.81 m/s²
r = Radius of turn = 25.5 m
When the car is on the verge of sliding we have the force equation
The speed of the car that will put it on the verge of sliding is 12.6332454263 m/s
