JEE Main 2019 — Work Power Energy Question with Solution
JEE Main 2019 (09 Jan Shift 1)
Question
A block of mass lying on a smooth horizontal surface, is attached to a spring (of negligible mass) of spring constant The other end of the spring is fixed, as shown in the figure. The block is initially at rest in its equilibrium position. If now the block is pulled with a constant force the maximum speed of the block is:

Correct answer
A
Step-by-step explanation
When block attains maximum speed net force on is zero.
Or
From work energy theorem
