Answer:
h = 219.96 m
Explanation:
Speed of the stone with which it was thrown horizontally, v = 10 m/s
We need to find the height of the cliff if the stone’s trajectory time from the top of the hill to the bottom to be 6.7s.
It means we need to find the distance covered by the stone. As the horizontal speed of the stone is given , it means there is no vertical motion in the stone,u'=0
Using second equation of motion,
Put u'=0 and a=g
So,
So, the height of the cliff is 219.96 m.
Net centripetal force is given by the product of mass and centripetal acceleration
Here we know that
mass (m) = 20 kg
speed (v) = 10 m/s
radius (R) = 15 m
So here we can say that centripetal acceleration is given as
now from the formula of force
<em>so correct answer would be 133 N</em>
