A rubber toy duck is at rest on an inclined plane. When the angle of inclination of the plane is increased to 36.0°, the toy duc
ch4aika [34]

Answer

toy begins to slide when the plane is at an angle of 36.0°

at this point the toy has just overcome the static friction

f_s = \mu_s N

f_s = \mu_s mgcos \theta

since toy begins to slide

f_s = mgsin \theta

now on comparing

mgsin \theta = \mu_s mgcos \theta

\mu_s = tan \theta

\mu_s = tan (36^0)

\mu_s = 0.726

as the body is moving at constant velocity acceleration will be zero

so now,

m g sin \theta - f_k = ma

m g sin \theta - \mu_k mg cos\theta = 0

\mu_k = tan \theta

\mu_k = tan (29^0)

\mu_k = 0.554

What is the efficiency of a tractor that has a work output of 300j and a work input of 400j
Sauron [17]
<h3><u>Answer;</u></h3>

= 75 %

<h3><u>Explanation</u>;</h3>

To measure efficiency of a machine, compare the work output to work input.

Efficiency = Work output/ work output × 100 %

                = 300/400 × 100

                = 75 %

I am sitting on a train car traveling horizontally at a constant speed of 50 m/s. I throw a ball straight up into the air.
drek231 [11]

Answer:

Explanation:

I am sitting on a train car traveling horizontally at a constant speed of 50 m/s. I throw a ball straight up into the air. Before , the ball gets separated from my hand , both me the ball will be moving with velocity of 50 m /s in horizontal direction .

As soon as ball is separated from the hand , it acquires addition velocity in upward direction and acceleration in downward direction . This will give relative velocity to the ball with respect to me . So I will see the ball going in upward direction under  gravitational acceleration . It appears as if I am sitting at rest and ball is going in upward direction under deceleration . My motion at 50 m/s will have no effect on the motion of ball in upward direction , according to first law of Newton . It is so because ball too will be moving in forward direction with the same speed which will not be visible to me because I too am moving with the same speed.

If I  am  sitting at rest at home and I threw a ball straight up into the air , I will have the same experience of seeing ball going in similar way as described above.

A small 32-kilogram canoe broke free of its dock and is now floating downriver at a speed of 2.5 m/s. What is
marysya [2.9K]
<h3>Answer:</h3>

80 kgm/s

<h3>Explanation:</h3>

<u>We are given;</u>

  • Mass of the Canoe is 32 kg
  • Speed of the Canoe is 2.5 m/s

We are required to calculate the momentum of the Canoe?

  • We need to know that momentum is the product of mass of an object and its speed.
  • Therefore;

Momentum = Mass × speed

Therefore;

Momentum = 32 kg × 2.5 m/s

                   = 80 Kgm/s

Thus, the momentum of the Canoe is 80 kgm/s.
