3 0

Answer:

Tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s

Explanation:

From the question above,

(1) tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s

Mometum = mass×velocity

Momentum = 270×0.5

Momentum = 135 kgm/s

(2) hare with a mass of 2.7 kg moving at a velocity of 7 m/s

Mementum = mass × velocity

Momentum = 2.7×7

Momentum = 18.9 kgm/s

(3) turtle with a mass of 91 kg moving at a velocity of 1.4 m/s

Momentum = mass × velocity

Momentum = 91×1.4

Momentum = 127.4 kgm/s

(4) roadrunner with a mass of 1.8 kg moving at a velocity of 6.7 m/s

Momentum = mass × velocity

Momentum = 1.8×6.7

Momentum = 12.06 kgm/s

From the above, the one with the greatest momentum is tortoise with a mass of 270 kg moving at a velocity of 0.5 m/s

Why do hurricanes rotate counterclockwise in the northern hemisphere
Genrish500 [490]

Answer:

A hurricane's spin and the spin's direction is determined by a super-powerful phenomenon called the Coriolis effect. It causes the path of everything from particles in the air to currents in the ocean so they curve as they travel across and over Earth's surfaces.

Point P is on the rim of a wheel of radius 2.0 m. At time t = 0, the wheel is at rest, and P is on the x-axis. The wheel undergo
oksian1 [2.3K]

Answer:

e). a = 0.066 m/s^2

Explanation:

As we know that wheel is turned by 90 degree angle

so the angular speed of the wheel is given as

\omega_f^2 - \omega_i^2 = 2\alpha \theta

now we have

\omega_f^2 - 0 = 2(0.01)(\frac{\pi}{2})

\omega = 0.177 rad/s

now the centripetal acceleration of the point P is given as

a_c = \omega^2 R

a_c = (0.177)^2(2)

a_c = 0.063 m/s^2

tangential acceleration is given as

a_t = R\alpha

a_t = 2(0.01)

a_t = 0.02 m/s^2

now net acceleration is given as

a = \sqrt{a_t^2 + a_c^2}

a = \sqrt{0.02^2 + 0.063^2}

a = 0.066 m/s^2
