Answer:

The force magnitude is  

and it is directed at 57.98° from the horizontal in a counterclockwise manner.

Explanation:

The problem states that

At t = 0,

The angular rate of increase is

Converting to revolutions per second gives us  

The rope length is defined by

                         

    At , Tension T of the rope is 18 kN.

     The weight of the para-sailor is

In analyzing the question, we observe that the equation for length can be represented as a linear displacement equation.

 The derivative of displacement results in velocity.

Hence,

           

signifies the velocity, and further differentiation yields acceleration.

Therefore,

         

Now considering the moment when the rope forms a 30° angle with the water,

typically angular velocity is expressed as

                     

where represents the angular displacement.

Next, evaluating the interval from gives us

                 

making t the focal point.

             

               

At this time, the displacement measures

               

               

The linear velocity computes to

             

               

Whereas linear acceleration calculates as

         

             

Generally, radial acceleration is given by

         

             

             

Simultaneously, angular acceleration can be represented as

                 

Then

Thus,

             

                   

The resultant acceleration is mathematically denoted as

               

                 

                 

Now the acceleration's direction is mathematically expressed as

                 

                       

                           

               

The y-axis force acting on the para-sailor is mathematically shown as

               

                   

                   

The x-axis force acting on the para-sailor is represented as

                 

             

             

The overall force is calculated as

                     

                             

                           

The directional force is evaluated as

             

                   

                       

                       

     

                     

Answer:

The correct response is:

1. KE Increases, PE Increases, ME Increases.

Explanation:

In this context, kinetic energy refers to the energy associated with an object's motion. Kinetic energy can be defined as the energy required to accelerate a mass from rest to a specified velocity, which it maintains once that speed is reached:

KE = 1/2 mv².

This definition indicates that KE is on the rise.

Potential energy is the energy stored in a body due to its position in a gravitational field:

PE = mgh,

which increases as the object is elevated against gravitational pull.

Since both kinetic and potential energies are increasing, it follows that the total mechanical energy (ME) is also rising:

ME = PE + KE.

Answer:

Statements 4, 6 & 7 are incorrect.

Explanation:

In any elastic collision, the overall momentum vector sum of the system remains zero.

In this scenario, an elastic collision occurs between the ball and a stationary wall. The ball's velocity will consistently revert after the impact, leading to a change in direction of momentum.

The initial momentum of the ball is represented as:

where:

m = mass of the ball

v = initial velocity of the body

post-collision for the elastic interaction:

• Here, the momentum changes solely in direction, thus contradicting statement 7.

• During the impact, both the ball and the wall exert forces on each other that are equal and opposite. The wall remains motionless, while the ball is influenced by the wall's reaction force, performing work on it, which contradicts statement 4.

• Given that this collision is elastic, the ball's form and dimensions do not alter.

• The previous points clearly indicate that not all provided statements hold true, thus violating statement 6.

Recall this formula for a device operating in a direct current circuit:
P = IV
In this equation, P stands for the power emitted by the device, I signifies the current passing through the device, and V represents the voltage drop across it.

Using ampere for current and volt for voltage means that multiplying current by voltage gives you power measured in watts.
