Question
a particle is moving along a straight line such that its position varies with time t as x=6α [ t+ αsin (t/α)
where x is its position in metre, t is time in s and α is a positive constant
The particle comes to rest at time t = (in terms of α and π)
Joshi sir comment
differentiating given x w. r. t. t
dx/dt will be v
for rest v = 0
