The downwards component of weight of the object would be 35sin25 degrees = 14.8
F=14.8 - 8 = 6.8 N m= 35/9.8= 3.57 kg
F=mA
Therefore,
3.57A= 6.8 N
=> A= 6.8/3.57
=> A= 1.902 ms^-2
F(max)= (U)R where (U)= coefficient of friction
and R= Normal reaction force
R= 35cos25
= 31.72 N
Since, F(max)= 8
8= (U)* 31.72
=>(U)= 8/31.72
=>(U)= 0.25
Helped us in modern days do to his contribution to the study of motion back in the day is what helpes us know how to study motion.
The centripetal force on the ball is 140.9 N; option A
<h3>What is the centripetal force on the ball?</h3>
The centripetal force on the ball is given by the formula below:
where;
- m is mass
- v is linear velocity
- r is radius
The linear velocity, v = wr
v = 5 * 2π/4.4 * 1.4 = 9.93 m/s
F = 10² * 2/1.4 = 140.9 N
In conclusion, the centripetal force is derived from the mass, velocity and radius of the path.

Hey there!
Okay so, the Lithosphere is made out of Earth’s outermost layer, which is composed of rocks in the crust and the upper mantle that behave as brittle solids.
The Mantle is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals.
The Core has two parts. The solid inner core made up of iron. The outer core is surrounded by a liquid composed of a nickel-iron alloy.
I hope this helps!
Heat can travel as<em> radiation</em>, even if there are no particles of matter
along the way. Which is really lucky, because that's how we get
heat from the sun. And light too.
