You're going to use the constant acceleration motion equation for velocity and displacement:
(V)final² = (V)initial²+2a(dx)
Given:
a=0.500m/s²
dx=6.32 m
(V)intial=0m
(V)final= UNKNOWN
(V)final= 2.51396m/s
Friction can be defined as a type of force that prevents two smooth surfaces from sliding together on each other. Friction is a strong force that oposses motion when two surfaces come in contact with each other.
The different methods/ways to reduce friction include;
- Application of lubricant to surfaces
- Streamlined bodies; this goes a long way in preventing friction between two bodies.
- Decrease in weight; reducing the amount of weight on a substance can also help to reduce friction
- Applying wheels to objects that move/roll on the ground.
Answer:
kE=0.0735 J
Explanation:
Given that
Radius ,R=10 cm = 0.1 m
Mass ,m= 3 kg
Angular speed ,ω = 3.5 rad/s
We know that moment of inertia for solid sphere given as
Kinetic energy
Now by putting the values
kE=0.0735 J
Therefore the kinetic energy will be 0.0735 J
