A fly sits on a potter's wheel 0.30 m from its axle. The wheel's rotational speed decreases from 4.0 rad/s to 2.0 rad/s in 5.0 s
earnstyle [38]

Answer:

0.4rad/s²

Explanation:

Angular acceleration is the time rate of change of angular velocity . In SI units, it is measured in radians per second squared (rad/s²)

w1 = 4rad/s, w2 =2rad/s, t = 5sec, r = 0.30m

a = ∆w/t

a = (w2 - w1)/t

a = (2 - 4)/5 = -2/5 =

a = - 0.4rad/s²

The -ve sign indicates a deceleration in the motion

Good luck

a. Find the magnitude of the gravitational force (in N) between a planet with mass 6.50 ✕ 1024 kg and its moon, with mass 2.45 ✕
Vanyuwa [196]

Answer:

a. 1.70\times 10^{20} N b. 6.94\times 10^{-3}m/s^2 c. 2.62\times 10^{-5} m/s^2

Explanation:

Use Gravitational Force:

F= G\frac{Mm}{r^2}

Use values given to have the results.

b.

g=\frac{F}{m}

Use m as the mass of the Moon. Using values of a. and m you have the answer.

c.

g = \frac{F}{M}

Use M mass of the planet. Use value of a and Mass of Planet.
