Question

A body of mass 0.5 kg is rotated in a circle of radius 1m with a uniform speed of 5m/s. Calculate the radial acceleration and the corresponding force.​

Answer 1

Answer:

radial acceleration = 25m/s2 ; force = 12.5N

Explanation:

for an object performing uniform circular motion, acceleration is given by

$a=\frac{v^{2} }{r}$, where v is linear velocity, r is radius of circle

in this case, v=5m/s and r = 1m

$a=\frac{v^{2} }{r} =\frac{5^2}{1}=25ms^{-2}$

force F=ma,

= 0.5*25

=12.5N
