Answer:

<em>The minibus traveled 75.66 km</em>

Explanation:

<u>Motion with Constant Speed </u>

An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.

The formula to calculate the speed is:

\displaystyle v=\frac{d}{t}

Where  

v = Speed of the object

d = Distance traveled

t = Time taken to travel d.

From the equation above, we solve for d:

d = v . t

The minibus has a constant speed of v=39 km/h and it's required to find the distance it travels in t=1.94 hours.

Calculating the distance:

d = 39 km/h * 1.94 h

d = 75.66 km

The minibus traveled 75.66 km

7. A rightward force is applied to a book in order to move it across a desk at
Snezhnost [94]

Answer:

See the explanation below

Explanation:

In the attached image we can see the free body diagram and forces acting on the book.

Force F, which acts to the right, the friction force which acts in the opposite direction to the movement, i.e. to the left.

The force exerted by the weight of the book that is equal to the product of the mass of the book by the gravity of the book. The normal force that is equal in magnitude to the weight of the book but in the opposite direction.

A badger is trying to cross the street. Its velocity vvv as a function of time ttt is given in the graph below where rightwards
hjlf

The badgers displacement from its position at point <em>t </em>= 2, to its position at point <em>t </em>= 3 is 25 meters

<h3>Which method can be used to calculate the displacement of the badger?</h3>

The points on the graph are;

(0, 0), (1, 5), (3, -5), (6, -5)

The point <em>t </em>= 2 is between (1, 5) and (3, -5)

The slope, <em>m</em>, of the line containing the point <em>t </em>= 2 is therefore;

  • m = (-5 - 5)/(3 - 1) = -5

The equation of the line is therefore;

v - 5 = -5•(t - 1)

v = -5•t + 5 + 5 = -5•t + 10

v = -5•t + 10

At <em>t </em>= 2, we have;

v = -5×2 + 10 = 0

The velocity at <em>t </em>= 2 is 0 m/s

The value of the acceleration is the same as the slope, <em>m </em>= a = -5

Given that the initial velocity at <em>t </em>= 2 is 0, we have;

∆x = u•t + 0.5•a•t²

At <em>t </em>= 3, the time of travel from the time <em>t </em>= 2 is 1 seconds, which gives;

∆x = 0×5 + 0.5×(-5)×1² = -2.5

The distance traveled between points,<em> </em><em>t </em>= 2 and <em>t </em>= 3 is ∆x = -2.5, which is 2.5 meters in the direction opposite to the initial direction.

An object is moving with constant non-zero velocity. Which of thw following statements about it must be true
hram777 [196]

Answer:

The net force on the object is zero.

Explanation:

An object is moving with constant non-zero velocity. If velocity is constant, it means that the change in velocity is equal to 0. As a result, acceleration of the object is equal to 0. Net force is the product of mass and acceleration. Hence, the correct option is (d) "The net force on the object is zero".
