Awashing machine drum 90.0 cm in diameter starts from rest and achieves 1200.0 rev/min in 24.0 s. assume the acceleration of the drum is constant. 1) calculate the magnitude of the net acceleration of a point on the drum after 1.00 s has elapsed. (express your answer to three significant figures.)

Explanation:

Given

Drum Radius=90 cm

radius =45 cm

N=1200 rev/min

Time(t)=24 s

Now radial acceleration

Tangential acceleration

Net acceleration after 1 sec will be

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
