Answer:
Explanation:
Both carts are modelled by using the Principle of Energy Conservation and Work-Energy Theorem:
Cart A:
By assuming a constant acceleration, final velocity is equal to:
Then,
Cart B:
By assuming a constant acceleration, final velocity is equal to:
The kinetic energy of cart B is 0.5K.
Answer:
r = 1.86 m
Explanation:
Here the force due to wall of the cylinder is towards the axis of the cylinder
This force will act as centripetal force for the people sit inside the chamber
now we will have
now we will have
m = 84.4 kg
v = 3.28 m/s
now we have
now we have
Answer:
The size of the image is 1.04 m.
Explanation:
Given that,
Height of object = 2.40 m
Distance of object = 2.60 m
Radius of curvature =4.00 m
Focal length
We need to calculate the image distance
Using mirror formula
We need to calculate the height of the image
Using formula of magnification
Put the value into the formula
Hence, The size of the image is 1.04 m
Answer:
α= 15.4[rad/s^2], 500 [rev/min]
Explanation:
La aceleración angular constante esta definida por la siguiente ecuación:
Para poder llegar a las 2000 [revoluciones /min] estando en 1500 [rev/min], la cuchilla tuvo que incrementar su numero de revoluciones a 500 [rev/min]. Mientras aceleraba.
