A car starts from rest and experiences a constant acceleration of 5 m/s2 until it reaches a speed of 650 meters

Zigmanuir [339]

Answer: Time.

Explanation:

Hey there!!!

The reason is,

According to the question we have,

Initial velocity = 0m/s { as it starts from rest}.

Final velocity = 650 m/s

acceleration = 5m/s^2.

Looking on this formula,

$a = \frac{v - u}{t}$

Where "v" represents final velocity, "u" represents initial velocity and "a" represents acceleration. We dont have is time "t".

So, it's obvious that tine is an unknown variable.

Hope it helps...

A cylindrical bucket, open at the top, is 28.0 cm high and 11.0 cm in diameter. A circular hole with a cross-sectional area 1.55

svlad2 [7]

Answer:

so height is 0.1283 m

Explanation:

given data

height = 28 cm

diameter = 11 cm

cross-sectional area = 1.55 cm2

water flow rate = 2.46×10^−4 m3/s

to find out

How high will the water in the bucket rise

solution

we know that here

potential energy = kinetic energy

mgh = 1/2 mv²

multiply both sides by the 2 and we get

2mgh=mv²

solve it we get

√(2gh) = v ....................1

h = v²/2g ...............2

and

flow rate = A V

2.46×10^−4 = V 1.55×10^−4

V = 1.5870 m/s

so from 2

h = v²/2g

h = 1.5870²/ 2(9.81)

h = 0.1283 m

so height is 0.1283 m
