Question

the displacement of an object attached to a spring and executing SHM is given by X equals to 2 into 10 to the power minus two Cos pi 3 the time at which maximum speed third time offer is​

Answer 1

your answer will be 0.5s

beacuse

x= $2=10^{-2}$

v=0.02$\pi$ t

v is maximum at t=

$\frac{1}{2} = 0.5sec\\\\\\ x= 2*10^{-2}cos\pi t \\v= 0.02\pi sin \pi t$

v is maximum at t=$\frac{1}{2}$=0.5sec
