Each wheel of a 320 kg motorcycle is 52 cm in diameter and has rotational inertia 2.1 kg m2 . The cycle and its 75 kg rider are

Amiraneli [1.4K]

Answer:

The value is $h = 32.91 \ m$

Explanation:

From the question we are told that

The diameter of each wheel is $d = 52 \ cm = 0.52 \ m$

The mass of the motorcycle is $m = 320 \ kg$

The rotational kinetic inertia is $I = 2.1 \ kg \ m^2$

The mass of the rider is $m_r = 75 \ kg$

The velocity is $v = 85 \ km/hr = 23.61 \ m/s$

Generally the radius of the wheel is mathematically represented as

$r = \frac{d}{2}$

=> $r = \frac{0.52}{2}$

=> $r = 0.26 \ m$

Generally from the law of energy conservation

Potential energy attained by system(motorcycle and rider ) = Kinetic energy of the system + rotational kinetic energy of both wheels of the motorcycle

=> $Mgh = \frac{1}{2} Mv^2 + \frac{1}{2} Iw^2 + \frac{1}{2} Iw^2$

=> $Mgh = \frac{1}{2} * Mv^2 + Iw^2$

Here $w$ is the angular velocity which is mathematically represented as

$w = \frac{v }{r }$

So

$Mgh = \frac{1}{2} * Mv^2 + I \frac{v}{r} ^2$

Here $M = m_r + m$

$M = 320 + 75$

$M = 395 \ kg$

$395 * 9.8 * h = 0.5 * 395 * (23.61)^2 + 2.1 *[\frac{ 23.61}{ 0.26} ] ^2$

=> $h = 32.91 \ m$
