A soccer player kicks a soccer ball initially at rest setting it in motion at a velocity of 30 m/s. If the ball has a mass of 0.
Alchen [17]

Answer:

 F= 600 N

Explanation:

Given that

Initial velocity ,u= 0 m/s

Final velocity ,v= 30 m/s

mass ,m = 0.5 kg

time ,t= 0.025 s

The change in the linear momentum is given as

ΔP= m (v - u)

ΔP= 0.5 ( 30 - 0 ) kg.m/s

ΔP= 15 kg.m/s

We know that from second law of Newtons

F=\dfrac{dP}{dt}

F=\dfrac{\Delta P}{t}

Now by putting the values

F=\dfrac{15}{0.025}\ N

F= 600 N

Please show steps as to how to solve this problem <br> Thank you!
bezimeni [28]

Explanation:

Let x = distance of F_1 from the fulcrum and let's assume that the counterclockwise direction is positive. In order to attain equilibrium, the net torque \tau_{net} about the fulcrum is zero:

\tau_{net} = -F_1x + F_2d_2 = 0

-m_1gx + m_2gd_2 = 0

m_1x = m_2d_2

Solving for <em>x</em>,

x = \dfrac{m_2}{m_1}d_2

\:\:\:\:=\left(\dfrac{105.7\:\text{g}}{65.7\:\text{g}} \right)(13.8\:\text{cm}) = 22.2\:\text{cm}
