Respuesta :
centripetal force = 533N
radius = 0.75 m
mass = 16.4 kg
How fast is rachel moving? we are looking for v = velocity
centripetal force = (mv^2)/r
533 = ((16.4)(v^2))/.75
cross multiply
(533)(.75) = (16.4)v^2
((533)(.75))/16.4 = v^2
v^2= 24.375
take the square root
v = 4.9
Rachel is moving at 4.9 m/s
radius = 0.75 m
mass = 16.4 kg

Rachel is moving at 4.9 m/s
Velocity of Rachel is 4.93 m/s
Given that;
Centripetal force = 533 N
Radius of circle = 0.75 m
Mass of Rachel = 16.4 kg
Find:
Velocity of Rachel
Computation:
Centripetal force = Mv² / r
So,
533 = [(16.4)(v²)] / 0.75
399.75 = (16.4)(v²)
v² = 399.75 / 16.4
v² = 24.375
v = √24.375
v = 4.93 m/s
