Question

saad has mass 80 kg when resting on the ground at the equator . what will be the centripetal acceleration on saad if the radius of the earth R is 6.4×10^6 m.

Answer 1

Here,
m=80 kg
R= 6.4*10^6 m
and t=24*3600=86400 s

Centripetal acceleration:
a=ω²r
=(2
`\pi` /86400)^2 * 6.4*10^6
=0.034 m/s²
