A large box containing your new computer sits on the bed of your pickup truck. You are stopped at a red light. When the light tu

rns green, you stomp on the gas and the truck accelerates. To your horror, the box starts to slide toward the back of the truck. Draw clearly labeled free-body diagrams for the truck and for the box. Indicate pairs of forces, if any, that are third-law action–reaction pairs. (The horizontal truck bed is not frictionless.)

Answer:

The description of that same situation has been listed throughout the explanation segment below.

Explanation:

  • When another huge box or container containing your new machine or device sits on someone's pick-up truck's bed, the third low portion of the operation response force.
  • This same friction force of the box mostly on the truck bed as well as the friction force including its truck bed on either the box from either the immune response pair.

So that the above seems to be the right answer.

A car drives over a hilltop that has a radius of curvature 120 m at the top of the hill. at what speed would the car be travelin
FinnZ [79.3K]
The speed of a car travelling over a hill that has a radius of curvature should not exceed a certain speed other it will topple. This speed is related to the radius of curvature and the gravitational acceleration as shown below:

V^2 = Rg, where V = maximum speed, R = Radius of curvature, g = gravitational acceleration.

Substituting;
V = Sqrt (Rg) =  Sqrt (120*9.81) = 34.31 m/s

If a 15kg mass weighs 372 N on Jupiter, what is Jupiter's gravitational acceleration?
Dimas [21]

Answer:

Jupiter's gravitational acceleration is 24.8 m/s^2

Explanation:

Recall that the weight under the influence of a gravitational acceleration G is defined as:

Weight = m * G

Then, in our case we have

372 N = 15 kg * G

G = 372/15  m/s^2

G = 24.8 m/s^2

A hockey puck is sliding across a frozen pond with an initial speed of 9.5 m/s. It comes to rest after sliding a distance of 37.
Bond [772]

Answer:

<h3>The coefficient of kinetic friction between the puck and the ice is \mu _{k} = 0.12</h3>

Explanation:

Given :

Initial speed  v_{o} = 9.5 \frac{m}{s}

Displacement x = 37.4 m

From the kinematics equation,

  v^{2} - v^{2} _{o}  = 2ax

Where v^{2}   = final velocity, in our example it is zero (v =0), a = acceleration.

   a =- \frac{90.25}{ 2 \times 37.4}

   a =- 1.21 \frac{m}{s^{2} }

From the formula of friction,

  F =- \mu _{k } N

Minus sign represent friction is oppose the motion

Where N = mg ( normal reaction force )

 ma = -\mu _{k}  m g                                                  ( ∵ g = 9.8 \frac{m}{s^{2} } )

So coefficient of friction,

 \mu_{k} = \frac{1.21}{9.8}

 \mu_{k} = 0.12

Therefore, the coefficient of kinetic friction between the puck and the ice is  \mu _{k} = 0.12 .
