Yes gravity would be the force that is holding that object down

Well, it seems as though there would be no forces, because it's "at rest", but wouldn't gravity still be acting upon it?

A disk, initially rotating at 120 rpm, is slowed down with a constant acceleration of magnitude 4 rad s2. If the disk has diamet

andrey2020 [161]

Answer:

Explanation:

given,

ω₁ = 120 rpm

1 rpm = $\dfrac{2\pi }{60} rad/s$

$\omega_1 =120\times \dfrac{2\pi }{60}$ rad/s

= 12.56 rad/s

α = - 4 rad/s²

diameter of disk = 20 cm

final angular velocity = 0

t = $\dfrac{\omega_f-\omega_i}{\alpha}$

t = $\dfrac{0-(12.56)}{-4}$

t = 3.14 s.

2) $\theta = \omega_i t +\dfrac{1}{2} \alpha t^2$

= $12.56\times 3.14 +\dfrac{1}{2}\times (-4)\times 3.14^2$

= 19. 72 radians

3) total angular distance rotated

x = θ R

x = 19.72 × 0.1 = 1.97 m

x = 2 m

calculate the gravitational force in between two objects of mass 25 kg and 20 kg if distance between them is 5m

sladkih [1.3K]

Answer:

Gravitational force is 1.33 × 10^-9 N

Explanation:

$force = \frac{GMm}{ {r}^{2} }$

${ \sf{ = \frac{6.67 \times {10}^{ - 11} \times 25 \times 20 }{ {5}^{2} } }} \\ \\ = { \sf{1.33 \times {10}^{ - 9} \: newtons }}$

distance is the length of his trip so 15( 3+4+8)

displacement is how far he is from his original point ( -5)( -4^2 + 3^2 = 5^2) he was displaced 5 meters from his start position
