The formula of the kinetic energy is:
where m is a mass of the object, v is speed of the object at the moment of time. So we have:
The answer is
2000 Joules.
The answer is 1.33 i hope this helps you
In Physics, 'work' has a very clear definition:
It's (strength of a force) times (distance through which the force acts).
'Work' has the units of Energy.
If you push against a shopping cart with 30 newtons of force, and
you keep pushing while the cart moves 4 meters, then you have
done (30 x 4) = 120 newton-meters of work = 120 "Joules".
-- Energy is never created or destroyed.
-- No energy is added to the pendulum during its swing.
-- If we ignore air resistance and friction, then no energy is lost
from the pendulum during its swing.
-- Therefore the total energy of the pendulum must be constant.
-- Any potential energy lost at any point in the swing
must show up as kinetic energy. If it had 484J at the top,
then it'll have 484J at the bottom.
Answer:
primary advantage of composite material are high strength, low weight, corrosion resistance
Explanation:
The primary advantage of composite material is
1) high strength - they are stronger in strength than commanly used material like steel and aluminium.
2)low weight - lighter than most of the material like woods and others metals
3) corrosion resistance - it resist extreme condition of weather and can be good place where handling of chemicals takes place.
