Question

A body is moving in a circular path of radius 20cm with a linear speed of 5m/s It's normal acceleration is

Answer 1

Normal acceleration = 125 m/s²

Given data :

A body is moving in a circular path of radius 20 cm with a linear speed of

5 m/s

To find :

Normal acceleration.

Formula used:

Normal acceleration = $\frac{V^2}{R}$

Where,       V = Velocity

                  R = Radius

Explanation:

 V = Velocity = 5 m/s

 R = Radius  =  20 cm =20 × $10^-^2$ =  0.2 m.

Normal acceleration = $\frac{V^2}{R}$

Normal acceleration = $\frac{5^2}{0.2}$

Normal acceleration = $\frac{25}{0.2}$

Normal acceleration = 125 m/s²

Answer 2

125ms-¹

Explanation:

V=5m\s

r=20cm=0.2m

a=v²÷r

a=5²÷0.2=125m\s²
