Answer:

Non-contact force are forces that exist(arise) without any form of contact between two objects.

Examples are ;

  1. : Magnetic Force ;is a force that attracts certain metal objects (like iron and iron filings) towards a magnet.
  2. Electrostatic Force ;s the force exerted by a charged body on another charged or uncharged body
  3. Gravitational force ; is a force exerted by the earth on all objects on it

Determine the moment of inertia of a 14.8 kg sphere of radius 0.752 m when the axis of rotation is through its center.
vfiekz [6]

Answer:

I=3.348Kgm^2

Explanation:

From the question we are told that:

Mass m=14.8kg

Radiusr=0.752m

Generally the equation for inertia is mathematically given by

I=\frac{2}{5}mR^2

I=\frac{2}{5}14.8*(0.752)^2

I=3.348Kgm^2

At what height h above the ground does the projectile have a speed of 0.5v?
maw [93]

Answer:

h=\dfrac{3v^2}{8g}

Explanation:

It is given that,

Speed of the projectile is 0.5 v. Let h is the height above the ground. Using the first equation of motion to find it.

v=u+at

v=u-gt

Initial speed of the projectile is v and final speed is 0.5 v.

0.5v=v-gt

t=\dfrac{v}{2g}

g is the acceleration due to gravity

Let h is the height above the ground. Using the second equation of motion as :

h=vt-\dfrac{1}{2}gt^2

h=v\dfrac{v}{2g}-\dfrac{1}{2}g(\dfrac{v}{2g})^2

h=\dfrac{3v^2}{8g}

So, the height of the projectile above the ground is \dfrac{3v^2}{8g}. Hence, this is the required solution.
