Question

An athlete rotates a 1.00-kg discus along a circular path of radius 1.09 m. The maximum speed of the discus is 17.0 m/s. Determine the magnitude of the maximum radial acceleration of the discus.

Answer 1

Answer:

a= 289 m/s²  

Explanation:

Given that

mass , m =1 kg

Radius of the path ,R= 1.09 m

The maximum speed ,V= 17 m/s

Lets take the maximum acceleration = a

The radial acceleration is given as

$a= \dfrac{V^2}{R}$

V=Velocity

R=Radius of the circular path

Now by putting the values in the above equation we get

$a= \dfrac{17^2}{1}\ m/s^2$

a= 289 m/s²
