Suppose you and a friend, each of mass 60 kg, go to the park and get on a 4.0-m-diameter merry-go-round. you stand on the outside edge of the merry-go-round, while your friend pushes so that it rotates once every 6.0 s. what is the magnitude of the (apparent) outward force that you feel?
a. 7 n
b. 63 n
c. 130 n
d. 260 n

The magnitude of centripetal force is 130 N.

Explanation:

It is given that,

Mass, m = 60 kg

Diameter of the merry go round, d = 4 m

Radius, r = 2 m

Time for rotation, t = 6 s

We know that we will feel some of the outward force and this force is known as centripetal force. Its formula is given by :

v is the velocity

v = 2.09 m/s

F = 131.04 N

or

F = 130 N

So, the magnitude of centripetal force is 130 N. Hence, this is the required solution.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
