GPE = mgh

So we are looking for an answer with a height involved with it:

A bicycle moving horizontally has no height above earth's surface (assuming earth's surface is our 0 reference point), so therefore it has no GPE. It would have KE however.

A horse slowing down from a run: no mention of height so therefore no GPE, KE however is present

A beaker sitting on the floor has no KE or GPE.

So an apple about to fall from a tree branch is the best example of GPE because a tree branch usually has a height to it meaning that GPE is present.

Answer:

2482 Kg.m/s

Explanation:

Momentum is a product of mass of an object and its velocity with consideration to the direction of velocity and expressed as, p=mv where m represent mass of the ostrich and v is the velocity in m/s, p is momentum.

Substituting the mass of ostrich with 146 kg and the velocity as 17 m/s then the momentum of the ostrich is equal to

P=146*17=2482 kg.m/s

Therefore, the momentum of ostrich is equal to 2482 kg.m/s

A small particle has charge -2.00 uC and mass 1.50×10-4 kg. It moves from point A, where the electric potential is V(A) = 200 V,
Svet_ta [14]

Answer:

v_b=6.13 m/s..

Explanation:

Since no external force is acting on the system.

Therefore, Total energy remains constant before and after.

So, Total energy of system= energy due to potential applied+kinetic energy

T.E=qV_a+\dfrac{1}{2}mv_a^2=qV_b+\dfrac{1}{2}mv_b^2\\\dfrac{1}{2}mv_b^2=\dfrac{1}{2}mv_a^2+q(V_a-V_b)\\

(Here v=velocity ,V=potential ,q=charge and m=mass).

Putting values .

We get,  v_b=6.13 m/s..

At point B charged particle is moving faster as compared to point A.

Hence, it is the required solution.

A helicopter goes straight up 500m from a landing pad. It then goes north 20m. Then it goes down 452m. a) What is the displaceme
gavmur [86]

Answer:

a

  x-component             20 \  m

y-component     500 -  452 =  48 \  m

b

 Magnitude d  =  52 \  m

direction is  \theta  = 67.4^o

Explanation:

From the question we are told that

   The first  vertical distance is  y_1   = 500 \  m

    The  first horizontal distance  is  x =  20 \  m

    The  second vertical distance is  y_2  =  452 \  m

Generally the displacement is  

x-component             20 \  m

y-component     500 -  452 =  48 \  m

Generally the helicopters displacement is mathematically evaluated as  

       d  =  \sqrt{ x- component ^2  +  y- component ^2 }

      d  =  \sqrt{ 20t ^2  + 48 ^2 }

      d  =  52 \  m

The  direction is the angle the displacement of the helicopter makes with the horizontal which is mathematically evaluated as

         \theta  = tan ^{-1}[ \frac{48}{20}]

=>       \theta  = tan ^{-1}[ 2.4 ]

=>      \theta  = 67.4^o
