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
It's called Throat. You can refer the figure attached.
Answer:
C Thy make the force exert all at once
Answer:
v = 7.67 m/s
Explanation:
Given data:
horizontal distance 11.98 m
Acceleration due to gravity 9.8 m/s^2
Assuming initial velocity is zero
we know that
solving for t
we have
substituing all value for time t
t = 1.56 s
we know that speed is given as
v = 7.67 m/s
