ASHA 777 [7]

Answer:

194 kg m²

Explanation:

Use parallel axis theorem:

I = I₀ + mr²

I = 25 kg m² + (1 kg) ((5 m)² + (12 m)²)

I = 25 kg m² + 169 kg m²

I = 194 kg m²

A rocket initially at rest accelerates at a rate of 99.0 meters/second2. Calculate the distance covered by the rocket if it atta

Jobisdone [24]

Answer: The correct answer is option b.

Explanation: We are given that the rocket is at rest initially final velocity is 445m/s.

The acceleration of the rocket is $99.0m/s^2$

To calculate the distance of rocket, we use third equation of motion, which is:

$v^2-u^2=2as$

where, v = final velocity = 445m/s

u = initial velocity = 0m/s

a = acceleration = $99m/s^2$

s = distance = ? m

Putting values in above equation, we get:

$(445)^2-(0)^2=2(99)s\\\\s=1\times 10^3meters$

Answer:

Centripetal acceleration will be equal to $10.66m/sec^2$

Explanation:

We have given time taken to cover 180° is 0.5 sec

So time taken by 360° is equal to = 2×0.5 = 1 sec

Radius of the circle r = 0.520 m

So distance $d=2\pi r=2\times3.14\times 0.520=3.2656m$

So velocity $v=\frac{distance}{time}=\frac{.2656}{1}=3.2656m/sec$

We have to find the centripetal acceleration

Centripetal acceleration will be equal to $a_c=\frac{v^2}{r}=\frac{3.2656^2}{1}=10.66m/sec^2$

So centripetal acceleration will be equal to $10.66m/sec^2$
