As the tension in the rope is constant therefore the boat engine will also be pushing the boat with the same force as that of the drag force that is given to be 450 Newton.
<h3>What is a drag force?</h3>
Drag force is similar to friction force but is experienced by a moving body in a fluid. Direction of drag force is a positive to the direction of motion.
<h3>What is centripetal force?</h3>
Centripetal force is not a new force in nature but a manifestation of some force that causes rotation of a body.
Given:
Mass of the boat = 531 kg
Tension in the cable = 12900 Newton
Drag force experienced by the boat = 450 N
The boat along with the man is rotating using a cable which experiences a constant tension of 12900 Newton.
The boat's engine should also be generating a force perpendicular to the circular path travelled by the boat.
Now the tension in the string is constant this implies that all the force that the both engine is generating is being used in balancing the drag force exerted by water on the boat.
Therefore, the force produced by the engine will be equal to 450 Newton which will be used to balance the drag force.

For this case we have that the final speed is given by:
Where,
a: acceleration
vo: initial speed
t: time
Clearing the time we have:
Substituting values we have:
it takes 4.375 s for the car to stop
Answer:
false
Explanation:
because they does'nt Work for anything, are like they are not there
Answer:
t = 0.196 s
Explanation:
The speed of a pulse is determined by the characteristics of the medium, its density and its resistance to stress, as long as these remain the speed will be constant for which we can use the kinetic expressions of the uniform movement
v = x / t
t = x / v
calculate
t = 2/102
t = 0.196 s
The plum pudding model, which has been abandoned since the discovery of the nucleus, stated that electrons were embedded in a "mush" of positive material. The nuclear model says they are placed around a central nucleus.
