A 43-N crate is suspended from the left end of a plank. The plank weighs 21 N, but it is not uniform, so its center of gravity d

oes not lie halfway between the two ends. The system is balanced by a support that is 0.30 m from the left end of the plank. How far to the right of the support is the plank

Answer:

d_{2}=0.585m

Explanation:

The torque is the force by the distance so to determinate that both torque are the same magnitude so

T_{1}-T_{2}=0

T_{1}=T_{2}

F_{1}*d_{1}=F_{2}*d_{2}

43N*0.30m=21N*d_{2}

Solve to d2

d_{2}=\frac{41N*0.30m}{21N}

d_{2}=0.585m

Two soccer players kick the same 2-kg ball at the same time in opposite directions one kicks with a force of 15 n the other kick
Illusion [34]
Because the direction of the kicks are opposite, the net force between the applied forces is their difference.
                        Fn = F₂ - F₁
Substituting,
                        Fn = 15 N - 5 N
                        Fn = 10 N

From Newton's second law of motion,
                       Fn = m x a
where m is mass and a is acceleration. Manipulating the equation so that we are able to calculate for a,
                       a = Fn / m

Substituting,
                      a = (10 N) / 2 kg
                       a = 5 m/s²

<em>ANSWER: 5 m/s²</em>

A simple pendulum 2 m long swings through a maximum angle of 30 ? with the vertical.
Alexus [3.1K]
The complete question was calculate the period T assuming the smallest amplitude.
Using the equation;
T = 2 π√(L/g)
Where T is the period in seconds, L is the length of the rod or wire in meters and g is the acceleration due to gravity. 
Hence; T = 2×3.14 × √(2/9.81)
                = 6.28 × 0.4515
                = 2.836 seconds
