How ocean currents effect temperature and the amount of moisture of the air mass above coastlines

How could Sam determine the distance he drove and the true displacement between the two locations

irina1246 [14]

Distance is the physical length travelled. While the displacement is the shorter distance between any two given points.

<h3>What is distance?</h3>

Distance is a numerical representation of the distance between two objects or locations.

Distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.

Displacement is defined as the shortest distance between the two points.

Sam determines the distance by doing the calculation as;

distance = speed × time

Hence, the Sam determines the distance and displacement by the respective formulas.

The velocity of a 640-kg auto is changed from 10.0 m/s to 44.0 m/s in 71.0 s by an external, constant force. (a) What is the res

n200080 [17]

Answer:

(a) change in momentum of the car = 21760 kgm/s

(b) The magnitude of the force = 306.48 N

Explanation:

(a)

Change in momentum: This is the product of mass and change in velocity. The unit of momentum is kgm/s. It can be expressed mathematically as,

Change in momentum of the car = m(v-u)................. Equation 1

Where m = mass of the car, v = final velocity of the car, u = initial velocity of the car.

Given: m = 640 kg, v = 44.0 m/s, u = 10.0 m/s.

Substituting these values into equation 1,

Change in momentum of the car = 640 (44-10)

change in momentum of the car = 640× 34

change in momentum of the car = 21760 kgm/s

change in momentum of the car = 21760 kgm/s

(b) Force: Force of a body can be defined as the product of mass and its acceleration. It is measured in Newton (N). It can be expressed mathematically as,

Force = ma ................................ Equation 2

 Or

Force = m(v-u)/t...................................... Equation 3

Where m = mass of the car, v = final velocity of the car, u = initial velocity of the car, a = acceleration of the car, t = time taken to change the velocity.

Given: m = 640 kg, u = 10.0 m/s v = 44 m/s, t = 71 s.

Substituting these values into equation 3

Force = 640(44-10)/71

Force = (640×34)/71

Force = 306.48 N

The magnitude of the force = 306.48 N

A negative velocity, approaching zero, represents a negative acceleration. True or False

ruslelena [56]

Answer:

False.

Explanation:

Lets assume our positive direction to the right (this reasoning works for any direction). A negative velocity would then be then directed to the left. If it varies as such that it aproaches to zero, it means that the variation is directed to the right, and that is where the direction of the acceleration must be pointing. In other words, its losing its velocity, so the acceleration must point opposite to the velocity. Then it means the acceleration is positive.
