(Irodov). A particle moves along the x axis according to the law x
= a cos wt. Find the distance that the particle covers during the
time interval from t = 0 to t.
the Q factor of a sonometer wire is 2 x 10³ . on plucking it makes 240 vibrations per second. calculate the time in which amplitude decrease to half the initial value.
a car from rest and moves with constant acceleration.the ratio of distance covered by the car in nth second to that covered in n seconds is
