Question

A particle is oscillating according to the equation X = 7 cos 0.5, where t is in second. The point moves from the position of equilibrium to maximum displacement in time
​

Answer 1

The point move from the position of equilibrium to  maximum in 1sec time

Explanation:

Given X = 7cos0.5t where t is the time in sec

As we know the equation  for displacement X = Acoswt

then to find the value of T

we have T = 2π/w

T = 2π/0.5π = 4 sec According to given value,

then the time from eqilibrium to maximum is T/4 i.e = 4/4 = 1sec
