Use Newton's 2nd law of motion.
Here it is:
Force = (mass) x (acceleration)
= (80 kg) x (-5 m/s²)
= -400 Newtons .
I called the acceleration negative because the player is slowing down.
The force comes out negative because it's in the direction opposite to
his motion.
It works by you putting leverage on one side makes more force go to the other side so if you put a crowbar in between a door and you push on one side the other will push the opposite side with more force<span />
Answer:
The ring particles are made almost entirely of water ice, with a trace component of rocky material.
Explanation:
Answer:
C.
Explanation:
Force = Mass * Acceleration
So 20 = 5* Acceleration
4 = Acceleration
Answer:
(a) Ratio of mean density is 0.735
(b) Value of g on mars 0.920
(c) Escape velocity on earth is
Explanation:
We have given radius of mars and radius of earth
Mass of earth
So mass of mars
Volume of mars
So density of mars
Volume of earth
So density of earth
(A) So the ratio of mean density
(B) Value of g on mars
g is given by
(c) Escape velocity is given by
