Question

In the above equation 10.26 the author has taken first three terms of the equation 10.25 zero

I dont want the solved solution to this question

BUT please just tell me why the author is taking 1st three terms of equation 10.25 as zero in the solution?

394 10 MOTION IN A NONINERTIAL REFERENCE FRAME EXAMPLE 1O.2 A student is performing measurements with a hockey puck on a large merry- go-round with a smooth (frictionless) horizontal, flat surface. The merry-go- round has a constant angular velocity ? and rotates counterclockwise as seen from above. (a) Find the effective force on the hockey puck after it is given a push. (b) Plot the path for various initial directions and velocities of the puck as observed by the person on the merry-go-round that pushes the puck. Solution. The first three terms for Feff in Equation 10.25 are zero, so the effec- tive force as observed by the person on the merry-go-round is (10.26) We have taken the frictional force to be zero. Remember that v, is the velocity as measured by the observer on the rotating surface. The effective accelera- tion is (10.27) The

Explanation / Answer

As of now the motion using the fixed reference axis and the measurements made with respect to the moving reference system. Therefore the translation as well as angular motion are zero and the net force is also become zero.
