To develop this problem it is necessary to apply the equations concerning the conservation of the moment.
By definition the moment can be expressed in two ways,
The first as a function of force and because of time, that is
And also based on mass and speed
Speed 1 is moving in the opposite direction to our reference system and it remains constant, as is the mass therefore
Equation both expression we have that,
Therefore the speed of the glider is 2m/s
When Jane is sliding down a slide, she is demonstrating translational motion.
Answer:
Living means something which biologically active, and can function naturally.
Non loving is something which cannot function naturally and biologically.
Dead is something that was living for a certain period, but now it doesn't.
Answer:
Explanation:
Radius of the ball is
Initial speed of the ball is
Initial angular speed of the ball is
Coefficient of kinetic friction between the ball and the lane
is
Due to the presence of frictional force, ball moves with
decreasing velocity.
(a)
velocity in terms of is
(b)
Ball's linear acceleration is given by
(c)
During sliding, ball's angular acceleration is calculated as
(d)
The time for which the ball slides is calculated from the
equation of motion is
(e)
Distance traveled by the ball is
(for)
The speed of the ball when smooth rolling begins is
The answer would be weight in pounds
