A bus is moving at a speed of 150km/hr. Begins to slow at a constant rate of 3.0m/s each second. Find how far it goes before sto
ladessa [460]

Answer:

Distance = 13.9 meters

Explanation:

Given the following data;

Maximum speed = 150 km/hr to meters per seconds = 150 * 1000/3600 = 41.67 m/s

Decelerating speed = 3m/s

To find the distance travelled with this speed;

Distance = maximum speed/decelerating speed

Distance = 41.67/3

Distance = 13.9 meters

Therefore, the bus would travel a distance of 13.9 meters before stopping.

In the deep ocean, a water wave with wavelength 95 m travels at 12 m/s. Suppose a small boat is at the crest of this wave, 1.2 m
dimaraw [331]

Answer:

the vertical position is 1.1971m

Explanation:

Recall that

y = 1.2 * cos (\frac{2*\pi * distance travelled}{wavelenght})

recall that v = \frac{distance}{time}

thus;  distance =  v* t

this implies that distance = 12 * 5.0

                                          =  60

therefore;  y = 1.2 cos \frac{2*3.142*60}{95}

                  y = 1.1971m

Find the x-component of this
Mashcka [7]

The horizontal or x component of the vector is 53.5 m.

<h3>What is the x component?</h3>

We know that a vector quantity must posses both magnitude and direction. In this case, of a vector is inclined at an angle then the vector could have a vertical and a horizontal component. Recall that vector may have have;

- A vertical component

- A horizontal component

Recall that when we resolve a vector, we are able to obtain the effective component of the vector in the given direction. It could be vertical or horizontal.

The horizontal component of the vector is V cos θ where V is the numerical value of the vector.

Thus the horizontal component is;

55.1 m Cos 13.9 = 53.5 m
