A dad pushes tangentially on a small hand-driven merry-go-round and is able to accelerate it from rest to a frequency of 18 rpm,

puteri [66]

Answer:

F = 176.175 N

Explanation:

given,

radius of merry - go - round = 2.7 m

mass of the disk = 800 kg

speed of the merry- go-round = 18 rpm

= 18 $\dfrac{2\pi }{60}$

= 1.88 rad/s

time = 13 s

mass of two children = 25 kg

ω = ω₀ + α t

1.88 = 0 + α(13)

α = 0.145 rad/s²

we know

τ = I α

so,

$I = \dfrac{1}{2}MR^2+ 2 MR^2$

$I = \dfrac{1}{2}\times 800 \times 2.7^2+ 2\times 25\times 2.7^2$

$I = 3280.5 kg.m^2$

τ = I α

τ = 3280.5 x 0.145

τ = 475.67 N m

τ = F x r

475.67 = F x 2.7

F = 176.175 N
