Force (in newtons) = mass (in kg) x acceleration (m/sec)
Therefore Force = 3kg x 5m/s ==> 15 newtons
----------------------------------
75 newtons = m x 10 ==> 7.5kg
I believe...?
Comets orbit the sun just like planets do. Except a comet usually has a very elongated orbit. Thanks to the laws of gravity comets obey the same laws. A comets orbit takes it very close to the sun and then far away again.
Answer:
see below
Explanation:
You will need t find the volume of the sphere
4/3 pi r^3 divide into the mass
1431 / (4/3 pi (5.8)^3) = 14 gm /cm^3
Here in this question as we can see there is no air friction so we can use the principle of energy conservation
now here we know that
now plug in all values in above equation
divide whole equation by mass "m"
so height of the ball from ground will be 1.35 m
