A particle of mass m is projected from point A with an initial velocity v0 perpendicular to line OA and moves under a central fo
rce F along a semicircular path of diameter OA. Observing that r = r0 cos θ and r 2 q = h, show that the speed of the particle is v = v0 /cos2 θ

Answer:
Step-by-step explanation:
From the attachment, we have:
Rotation: 180 degrees clockwise
Required
Find J', K' and L'
When a point (x, y)is rotated 180 degree clockwise, the resulting point is: (-x, -y)
So, we have:
Let's assume the number be x.
So, sum of a number and 10 can be written as x+10.
Now the given statement is "One half of the sum of a number and 10 ".
So, one half of x+10 can be written as
