Caleb is swinging rachel in a circle with a centripetal force of 533 n. if the radius of the circle is 0.75 m and rachel has a mass of 16.4 kg, how fast is rachel moving? round to the nearest tenth. m/s

4.3 m/s

Explanation:

The centripetal force is given by

where

m is the mass of the object

v is the speed

r is the radius of the circular trajectory

In this problem, we know:

- the centripetal force: F = 533 N

- the radius of the circle: r = 0.75 m

- the mass of the object (Rachel): m = 16.4 kg

Therefore, we can re-arrange the formula above to find the speed of Rachel:

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
