Density = Mass per unit Volume
that is,
D = m / V
Now,
We've been provided with,
Density = 790 kg/m³
Volume = 1250 litres = 1.250 m³
Now,
987.5 kg of mass will a 1250 litres tank will hold.

Answer:
Th average force impact is
Explanation:
From the question we are told that
The mass of the golf ball is
The angle made is
The range of the golf ball is
The duration of contact is
Generally the range of the golf ball is mathematically represented as
Here v is the velocity with which the golf club propelled it with, making v the subject
=>
=>
Generally the change in momentum of the golf ball is mathematically represented as
here u is the initial velocity of the ball before being stroked and the value is 0 m/s
=>
Generally the average force of impact is mathematically represented as
=>
=>
You're driving along, and you see the light turn red, 1/2 block
in front of you. You gently put on the brakes.
The car loses kinetic energy and slows down.
The brakes absorb the kinetic energy, and they heat up.
______________________________________
If you're, let's say, coming down a mountain or a really long
hill, then the potential energy you had at the top changes to
kinetic energy, little by little, as you come down. Whenever
the speed of the car gets too high, you push the brakes to
slow it down. Then you take your foot off of the brakes, and
let them cool.
If you don't do that, and instead you keep your foot on the brakes
all the time, then the brakes keep getting hotter and hotter, and
by the time you get to the bottom, you have flames shooting out
from the hubcaps and burning the paint off the fenders !
I only saw this happen once, many years ago, when I was in a car
coming down a long road from the top of a mountain in China.
Thank goodness I was not the person who was driving !
I would have been seriously embarrassed.
