A puck of mass 0.5100.510kg is attached to the end of a cord 0.827m long. The puck moves in a horizontal circle without friction

. If the cord can withstand a maximum tension of 126N, what is the highest frequency at which the puck can go around the circle without the cord breaking?

Answer:2.74 Hz

Explanation:

Given

mass Puck m=0.51 kg

length of cord L=0.827 m

Maximum Tension in chord T=126 N

as the Puck is moving in a horizontal circle so maximum Tension in the string will be equal to centripetal force

F_c=m\omega ^2L=T

126=0.51\times (\omega )^2\times 0.827

\omega =\sqrt{298.74}

\omega =17.28 rad/s

\omega =2\pi f

f=\frac{2\pi }{\omega }

f=2.74 Hz

A force gives a 5.0 kg object an acceleration of 2.0 m/s 2. The same force would give a 20 kg object an acceleration of _____. 0
Oksi-84 [34.3K]

m = 5 kg

a = 2 m/s²

to find the force that accelerates the 4 kg object @ 2 m/s²

F = ma = 5 kg x 2 m/s² = 10 N

To find what acceleration 10 N would give a 20 kg object

a = F/m = 10 N/20 kg = 0.5 m/s

Which of the following changes would decrease the coefficient of friction needed for this ride?
posledela
Friction occurs between two contacting surfaces. The coefficient of friction is very much dependent on the roughness of these surfaces. Some of the many ways in which the coefficient can be lessened or decreased are to lubricate the surface or make it shiny by eliminating the spikes which caused the roughness.

dolphi86 [110]
The watch hand covers an angular displacement of 2π radians in 60 seconds.

ω = 2π/60
ω = 0.1 rad/s

v = ωr
v = 0.1 x 0.08
v = 8 x 10⁻³ m/s
