You set a small eraser at a distance of 0.27 m from the center of a turntable you find in the attic and establish that when the
Licemer1 [7]

Answer with Explanation:

We are given that

Distance,r=0.27 m

Tangential speed=v=0.49 m/s

a.Angular speed ,\omega=\frac{v}{r}

Using the formula

\omega=\frac{0.49}{0.27}=1.8 rad/s

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

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

Time period,T=\frac{2\pi}{1.8}=3.49 s

b.Amplitude,A=Distance of small eraser from the center of a turnable =0.27 m

c.Maximum speed,V_{max}=0.49 m/s

d.Maximum acceleration=a=r\omega^2=0.27(1.8)^2=0.87 m/s^2

Grace pushes her foot against the wall with a force of 35 N while she stands
Airida [17]

Answer:

The correct answer is B. 0.64 m/s²

Explanation:

According to the Newton's Second law of motion acceleration of an object by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force.

Mathematically,

                           F ∝ a

                           F = ma

Given data:

Force = F = 35 N

Mass = m = 55 kg

acceleration = a = ?

                           F = ma

                           a = F/m

                           a = 35/55

                          a = 0.64 m/s²
