Its angular speePer NCERT §3.10, the centripetal acceleration of a particle in UCM depends linearly on which of these quantitiPer NCERT §3.10 historical note, the analysis of centripetal acceleration was first published in 1673 by whichA football kicked with speed $u = 20$ m/s at $30^\circ$ above horizontal has initial vertical component approxA stone is thrown at $45^\circ$ on level ground with speed $u = 10$ m/s. Using $g = 10$ m/s$^2$, the range is:A stone tied to a string is whirled in a horizontal circle at constant speed. Its acceleration is:A ceiling fan rotates at $120$ rpm. Its angular speed is approximately:
