Question
Please answer #2 and #8 if you can, thank you!
student Swlys a muss of 6.120 kq tied to
onc end of a Cord in a hol izontal Ccle OF
Padius l00m so that Its tangential speed s
2.00 m/s. What 15 the centripetal force acting
on the mass?
2./What centripetal force is naeded to keep a
12-kg mass mouing at a constant speed
of m/s in
a cucle having a radius
of (a) 4m; (6) &m?
. An auto having a mass of 1500 kg Makes
laturn on a banked circular track oF radieus
200m at a speed of 20 m15. What cent-
npetal force does the track erert -n the
quto?
4.Whart 1s the centripetal Force Gcting on each
Kilogram of an aire lane that 15 turnng
at 200 m/b 1n a horizontal circle OF
radius l0,000 m?
5A child having amass of 30 ky 5its
14.0m flom the center
Ohut 15 fotating with a peciod
urat is Hhe centrupetal force acting upon
the child?
of a merry-9o.cound
