Suppose you and a friend, each of mass 55 kg , go to the park and get on a 4.5-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 7.0 seconds. part apart complete what is the magnitude of the (apparent) outward force that you feel?

a. 12 n
b. 50 n
c. 100 n
d. 200 n

c. 100 N

Explanation:

= mass of each = 55 kg

= Time period of rotation = 7.0 sec

Angular frequency is given as

= Diameter of the merry-go-round = 4.5 m

Radius of the merry-go-round is given as

Magnitude of outward force is same as the centripetal force and is given as

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
