The velocity of a particle moving back and forth on a line is vequalsStartFraction ds Over dt EndFraction equals6 sine (2 t )StartFraction m Over sec EndFraction for all t. If sequals0 when tequals0, find the value of s when tequalsStartFraction pi Over 2 EndFraction sec.

s = 6 m

Step-by-step explanation:

The value of the velocity v is given as:

m/s

To find s, we have to integrate and apply the initial values of s = o when t = 0:

When t = π/2, s will be:

s = -3cos(2 * π/2) + 3

s = -3cos(π) + 3

s = -3(-1) + 3

s = 3 + 3

s = 6 m
