Answer by mimiwhatsup: B) Velocity is a vector and requires a direction to completely describe it.

Velocity is the speed and direction of an object in motion.

Explanation:

Speed : It is defined as the overall distance travelled by an object divided by total time taken. The mathematical expression is given by :

s=\dfrac{d}{t}

It is a scalar quantity i.e. it has only magnitude.

Velocity : It is defined as the total displacement (D) of the particle divided by total time taken. It can be given by :

v=\dfrac{D}{t}

It is a vector quantity. It have both magnitude and direction.

Out of given options, the statement that best explains the difference between velocity and speed is (B) i.e. "Velocity is a vector and requires a direction to completely describe it".

stiv31 [10]

Answer:

1398.12 N

Explanation:

We define the x-axis in the direction parallel to the movement of the truck  on and the y-axis in the direction perpendicular to it.

x-components  of the ropes forces

T₁x = 615N*cos31°=527.1579 N  :Tension in direction x of the rope of the car 1

T₂x= 961 N*cos25°=870.96 N  :Tension in direction x of the rope of the car 2

Net forward force exerted on the truck in the direction it is headed (Fnx)

Fnx = T₁x  + T₂x

Fnx = 527.1579 N  + 870.96 N

Fnx = 1398.12 N
