Answer #1

Speed of particle increase or decrease along the tangential component.hence 4.2 m/s^2 taken as Tangential accelartion.

In the given problem firstly we have to find accelartion along radius or radial accelartion using below formula

  

Where a= total acceleration

Now calculate speed of particle V using below formula

Radial accelartion,
