A physical pendulum in the form of a planar object moves in simple harmonic motion with a frequency of 0.290 Hz. The pendulum ha

BARSIC [14]

Answer:

1.4584 kg $m^2$

Explanation:

Time period of a physical pendulum is given by $T=2Π\sqrt{\frac{I}{mgd}}$

Here f=0.290 so $T=\frac{1}{F}=\frac{1}{0.29}=3.44827$

Mass =2.40 kg

d=0.300 m

g =9.8 m $sec^2$

So $3.448=2\times \pi \sqrt{\frac{I}{2.4\times 9.81\times 0.300}}=1.4584$ kg- $m^2$

So the moment of inertia of the pendulum about the pivot point will be 1.4584 kg- $m^2$

How long does it take for an 8 kg pumpkin to hit the ground if dropped from a height of 55 m.

Sati [7]

Answer:

t = 3.35 s

Explanation:

It is given that,

Mass of a pumpkin, m = 8 kg

It is dropped from a height of 55 m

We need to find the time taken by it to hit the ground.

Initial velocity of the pumpkin, u = 0

Using second equation of motion to find it as follows :

$h=ut+\dfrac{1}{2}at^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2(55)}{9.8}} \\\\t=3.35\ s$

So, it will take 3.35 seconds to hit the ground.

NeX [460]

Answer:

Venus

Explanation:

The terrestrial planets are the planets in the solar system which are closer to the Sun, compared to the Gaseous giants like Jupiter.

Venus is the planet that is near the Sun and is formed where the solar system's temperatures are very high.

Mercury is the planet which has a very thin atmosphere and so is very cold. Venus is a planet similar to Earth, but it has a dense atmosphere . So venus is hottest compared to other planets.

A rifle bullet with mass ma = 8.00 g strikes and embeds itself in a block with mass mb = 0.992 kg that rests on a frictionless,

Doss [256]

Answer:

the magnitude of the velocity of the block just after impact is 2.598 m/s and the original speed of the bullect is 324.76m/s.

Explanation:

a) Kinetic energy of block = potential energy in spring

½ mv² = ½ kx²

Here m stands for combined mass (block + bullet),

which is just 1 kg. Spring constant k is unknown, but you can find it from given data:

k = 0.75 N / 0.25 cm

= 3 N/cm, or 300 N/m.

From the energy equation above, solve for v,

v = v √(k/m)

= 0.15 √(300/1)

= 2.598 m/s.

b) Momentum before impact = momentum after impact.

Since m = 1 kg,

v = 2.598 m/s,

p = 2.598 kg m/s.

This is the same momentum carried by bullet as it strikes the block. Therefore, if u is bullet speed,

u = 2.598 kg m/s / 8 × 10⁻³ kg

= 324.76 m/s.

Hence, the magnitude of the velocity of the block just after impact is 2.598 m/s and the original speed of the bullect is 324.76m/s.
