Answer:

5m, 2 sec

Explanation:

y = A sin ( wt + ¢ ) ( general equation)

y = 5 sinπ (t + 4) ( given equation )

re-writng the above.....

y = 5 sin ( πt + 4π )

on comparing....

A = 5m & w = π

but....

w = 2π/ T

hence....

2π/ T = π

T = 2 sec

  •  \boxed{\bf{Amplitude,A = 5\:m}}

  •  \boxed{\bf{Time\:Period, T = 2\: sec}}

The given equation of motion is

 \:\:\:\: y = 5 sin[\pi (t + 4)]\:\:m

Standard equation of a particle in SHM is

 \:\:\:\: y = A sin(\omega t + \phi)

Comparing the equation, we get

Amplitude,  A = 5\:m

Angular Frequency,  \omega = \pi\:\:rad/s

So, Time Period(T) is given by,

 \:\:\:\:\: T = \frac{2\pi } {\omega}

 \to T = \frac{2\pi } {\pi}

 \to T = 2\: sec
