Respuesta :
The radial acceleration of the tip of this hand is 0.274 cm/s². The answer is expressed in centimeters per second squared.
What is acceleration?
The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The radial acceleration of the tip of this hand is found as;
[tex]\rm \omega = \frac{2 \pi}{60} \\\\ a_r= \omega^2r\\\\ a= (\frac{2\pi}{60} )^2\times 25\\\\a=0.274 \ cm/s^2[/tex]
Hence,the radial acceleration of the tip of this hand is 0.274 cm/s²
