The two parents shown in (Figure 1) exert upward forces

Physics
1 answer:
timama [110]3 years ago

Answer:

W = 83 [N] (weight)

Explanation:

We must clarify that the system is in static equilibrium, in such a way that we must perform a sum of forces on the Y-axis equal to zero, in order to determine the downward force corresponding to the weight of the child.

∑Fy = 0

F_{1}+F_{2}-m*g=0\\18+65=m*g\\m*g = 83 [N]

And the mass can be determined as follows:

m*g=83\\m = 83/9.81\\m=8.46[kg]

ANSWER THIS OR ILL GO TO YOUR HOME AND KIDDNAPP YOU FAMILY
Vikki [24]

Answer:

The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.

Two blocks of masses 6 kg and 5.5 kg are
sp2606 [1]

When you squish the spring, you put some energy into it, and after the cord
burns and they go boing in opposite directions, that energy that you stored
in the spring is what gives the blocks their kinetic energy.

But linear momentum still has to be conserved.  It was zero while they were
tied together and nothing was moving, so it has to be zero after they both
take off.

Momentum = (mass) x (velocity)

After the launch, the 5.5-kg moves to the right at 6.8 m/s,
so its momentum is
                               (5.5 x 6.8) = 37.4 kg-m/s to the right.

In order for the total momentum to be zero, the other block has to
carry the same amount of momentum in the opposite direction.

               M x V = (6 x speed) = 37.4 kg-m/s to the left.

Divide each side by  6 :      Speed = 37.4 / 6 =<em>  6.2333... m/s left</em>

(That number is  (6 and 7/30) m/s .)

A rectangular tank is filled with water to a depth of 4m. Calculate the pressure at the bottom of the tank. PLEASEEE HELP!!
Paul [167]

The pressure in a liquid at a given depth is called the hydrostatic pressure. This can be calculated using the hydrostatic equation:

P = ρgh

P = (1000 kg/m³)(9.8 m/s²)(4 m)

<h2>P = 39200 Pa</h2>

A car uses ____________________________ to move. Select one: a. energy b. pulls c. motion d. work
Fynjy0 [20]

Answer:

Option A.

Explanation:

The correct answer is Option A.

The car uses energy to move.

A car is a machine that converts energy locked in fuel like petrol or diesel and turn it into mechanical energy.

The energy produced from the combustion of gasoline is then used to move the shaft, which sends the power to the rear axle and the wheel starts to move.
