A discus thrower turns with angular acceleration of 50 rad/s2, moving the discus in a circle of radius 0.80m. Find the radial and tangential components of acceleration of the discus when the angular velocity is 10 rad/s. (80 m/s2, 40 m/s2).

The value of tangential acceleration  40

The value of radial acceleration

Explanation:

Angular acceleration = 50

Radius of the disk = 0.8 m

Angular velocity = 10

We know that tangential acceleration is given by the formula

Where r =  radius of the disk

= angular acceleration

⇒ 0.8 × 50

⇒ 40

This is the value of tangential acceleration.

Radial acceleration is given by

Where V = velocity of the disk = r

⇒ V = 0.8 × 10

⇒ V = 8

Radial acceleration

This is the value of radial acceleration.

the answer is b
