An object's location, velocity, acceleration, and direction can all be used to define motion.
Define velocity:
Velocity and speed describe how quickly or slowly an object is moving. We frequently encounter circumstances when we must determine which of two or more moving objects is going faster. If the two are travelling on the same route in the same direction, it is simple to determine which is quicker. It is challenging to identify who is moving the quickest when their motion is in the other direction. The idea of velocity is useful in these circumstances. Learn what velocity is, how it is measured, an example of velocity, and how it differs from speed in this article.

what would the wind speeds at a be if the hurricane is moving due east at a speed of 40 km/hr and the average wind speed of the hurricane was 215 km/hr?
The wind speed would be 255km/hr if the hurricane is moving east due east at a speed of 40 km/hr and the average wind speed of hurricane was 215 km/hr.
We must determine the localized wind speed at Point A because it is the end of the storm and has the highest velocity.
Speed at point A equals the combined speeds of the hurricane and the forward motion since point A is situated in the same rotational direction as the cyclone.
speed at point A = speed of hurricane + speed of forward

What is net force?
The vector sum of the forces that act on a particle as well as object is known as the net force in mechanics. The original forces' impact on the motion of the particle is replaced by the net force, which is a single force. In accordance with Newton's second law of motion, it causes the particle to accelerate at a rate equal to the sum of all those actual forces. In order to keep the object's jets moving underneath the original system of forces, it is possible to calculate the torque connected to the point of application of the a net force. As with all actual forces combined, its corresponding torque, or net force, is becoming the resultant force and affects the object's rotational motion.
This is because the two forces acting on the block (the 10 Newton force to the right and the 10 Newton force to the left) are equal in magnitude, thus canceling each other out. Therefore, the net force on the block is zero Newtons.

A 0.260 kg potato is tied to a string with length 2.50 m, and the other end of the string is tied to a rigid support. The potato is held straight out horizontally from the point of support, with the string pulled taut, and is then released.A) What is the speed of the potato at the lowest point of its motion? let g be = 9.80 m/s^2
The speed of the potato at its lowest point of motion which has a mass of 0.260 kg tied to a 2.50 m long rope is 7 m/s.
Law of conservation of energyBasically, the law of the conservation of energy is one of the laws of Physics which states that energy is eternal, so it can't change all the time, and has the same value both before something happens and after it happens. Well, the existence of this energy can also be changed in form with a magnitude that will always be the same. In this law of conservation of energy, the energy in question is kinetic energy, potential energy, mechanical energy, and others.
So, the kinetic energy of that potato will be equal to its potential energy when the string is pulled and the potato will be released.

in short-track speed skating, the track has straight sections and semicircles 16 m in diameter. assume that a 65 kg skater goes around the turn at a constant 13 m/s .
Part A
What is the horizontal force on the skater?
part B
What is the ratio of this force to the skater's weight?
The horizontal force on the skater is 1373 N
Define force.
An object experiences a push or pull as a result of interacting with another object called force. Each object is subject to a force whenever two objects interact. The two items no longer feel the force after the interaction ends.
The diameter of the semicircular portion of the track is 16 m.
Therefore its radius is, r = 8 m.
The tangential velocity of the skater is 13 m/s.
Therefore the angular speed is
ω = v/r = (13 m/s)/(8 m) = 1.625rad/s
The horizontal force on the skater is due to centripetal acceleration
a = r*ω² = (8 m)*(1.625 rad/s)² = 21.125 m/s².
The force acting on the 65-kg skater is
F = m*a = (65 kg)*(21.125 m/s²) = 1373 N
The ratio of this force to the skater's weight: 1373/65 is 21.125
