Question

An object of mass 2kg attached to a wire of length 5m is revolved in a horizontal circle if it makes 60 r.p.m. find its angular speed, linear speed,centripetal acceleration, centripetal force.

Answer 1

angular speed is equal to
$2\pi radians \: {s}^{ - 1}$
linear speed =10πm/s
centripetal force is equal to
$40 {\pi}^{2} \: newtons$
I think it's correct if it is wrong excuse me you didn't have that concepts yet now

Answer 2

Answer:

onject mass m=2kg

length=radius=5m

frequency=60r.p.m.

=60/60r.p.s.=1 r.p.s.

to find

w=?,v=?,a=?,Fc=?

solution =

w=2πn

=2π1

v=rw

=5×2π

=10π

a=rw^

=5 × 2π^

=5×4π

=20π

Fc=mv^/r

=2×10^π^/5

=2×100π^/5

=40π^

these is your answer

please you take units OK
