Explanation / Answer

given

T = 2.4 s

Vmax = 48 cm/s

A) we know, angular frequency, w = 2*pi/T

= 2*pi/2.4

= 2.618 rad/s

we know, Vmax = A*w

==> A = Vmax/w

= 48/2.618

= 18.3 cm or 0.183 m <<<<<<<<----------Answer

B) we can write equation for poistion,

x = A*cos(w*t)

at t = 0.3 s

x = 18.3*cos(2.618*0.3)

= 12.96 cm or 0.1296 m <<<<<<<<----------Answer
