Amerry-go-round moves in a circle at a constant speed. is the merry-go-round accelerating? explain your answer.

Circular motion is defined as the motion or movement of an object at constant angular velocity.

For example, the merry-go-round is a type of circular motion along a fixed axis that undergoes acceleration.

Merry-go round is a type of swing in which the circular disc around a pole rotates constantly. It shows the circular motion. In this motion, the angular velocity of an object is constant, but the linear velocity is always changing.

The object in the circular motion, thus, will always be accelerating due to constant change in the linear velocity.

Therefore, the merry-go-round does exhibit circular motion along a fixed pole, but it always changes direction and is accelerating due to changes in linear motion.

Therefore, the merry-go-round undergoes acceleration.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
