Answer:
Explanation:
Given
Initial Flow of water
density
Initial velocity
Final velocity
Initial mass flow rate
Let area of cross section of Two streams after striking be A
Conserving Flow
or Flow rate after splitter splits in to half
conserving momentum in x direction
Final momentum in x direction
Change in momentum
F=1409.24 lbf
change of momentum in Y direction is zero as the two flows oppose thier motion after striking with splitter.
Answer:
The centripetal force on the boy = 2.888 N
Explanation:
Given:
m = 30 kg
r = 1.5 m
v = 0.38 m/s
To Find:
The centripetal force on the boy = ?
Solution:
F = m x v^2 / r
F = 30 kg x (0.38 m/s)^2 / 1.5 m
F = 30 x 0.1444 / 1.5
F = 2.888 N
Therefore,
The centripetal force on the boy = 2.888 N

Answer:
Velocity of truck will be 20.287 m /sec
Explanation:
We have given mass of the truck m = 4000 kg
Radius of the turn r = 70 m
Coefficient of friction
Centripetal force is given
And frictional force is equal to
For body to be move these two forces must be equal
So
Answer:
It takes <u>2.93 s</u> for the object to reach ground from the height of 42 m.
Explanation:
Given:
Displacement of the object is,
As it is dropped, initial velocity of the object is,
Acceleration of the object is equal to acceleration due to gravity and is equal to,
Now, using Newton's equation of motion and plugging in the values, we get:
So, it takes 2.93 s for the object to reach ground from the height of 42 m.
