Answer:
85.8 rad/min
Explanation:
Centripetal acceleration: This is the acceleration of a body in circular motion, and it tends towards the center of the circle. The S.I unit of centripetal acceleration m/s²
The formula of centripetal acceleration is given as,
a = ω²r............. Equation 1
Where a = acceleration, r = radius, ω = angular velocity.
make ω the subject of the equation
ω = √(a/r) ............. Equation 2
Given: r = 6.5 m, a = 1.55×9.8 = 13.23 m/s²
substitute into equation 2
ω = √(13.23/6.5)
ω = √2.035
ω = 1.43 rad/s = (1.43×60) rad/min = 85.8 rad/min
