Feng and Isaac are riding on a merry-ground. Feng rides on a horse at the outer rim of the circular platform, twice as far from
kogti [31]

Answer: The question is incomplete or missing details. here is the remaining part of the question ;

1. impossible to determine

2. half of Isaac’s

3. the same as Isaac’s

4. twice Isaac’s

The angular speed of feng will be the same as that of Isaac. Hence the answer is option 3

Explanation:

Since we have been told that both feng and isaac are riding on a merry go round i.e in a circular motion, irrespective of how fast one ride above the other, the angular speed will be constant since they are riding on a merry go round, as such both feng and isaac will maintain equal angular speed, hence the angular speed of feng will be the same as that of Isaac.

A boy on the edge of a vertical cliff 20-m high throws a stone horizontally outwards with a speed of 20 m/s. It strikes the grou
Komok [63]

Answer:

Horizontal distance from the foot of the cliff is 40 m

Explanation:

Given :

Speed of stone v = 20\frac{m}{s}

Vertical distance d = 20 m

Gravitational acceleration g = 10 \frac{m}{s^{2} }

From the kinematics equation,

  d = v_{o} t + \frac{1}{2} at^{2}

Where v_{o} = initial velocity ( v_{o} = 0 )

So time take to fall down,

  t = \sqrt{\frac{2d}{a} }

  t = \sqrt{4}

  t = 2 sec

Now find horizontal distance travel by stone,

 x = vt

 x = 20 \times 2

 x = 40 m

Therefore, the horizontal distance travel by stone is 40 m
