Question

A body vibrate in s.h.m with a frequency of 50Hz and a mplitude of 4cm.find the period,the acceleration at the middle and at the end of the path oscillation,the velocity at the middle and at end of path of oscillation

Answer 1

5 cm = 0.05 meters
T = period = 1/50 = 0.02 second
x = 0.05 sin 2 pi t/T = 0.05 sin 314 t
v = 0.05(314) cos 314 t
a = -0.05 (314)^2 sin 314 t
Now you should be able to figure it out

Answer 2

answer

Answer 3

That is not the Question

Answer 4

A body vibrate in SHM with a frequency of 5ohertz and amplitude of 4cm. Find:-
1. the period
2. the acceleration at the middle and at the end of the path of oscillation
3. the velocities at the middle and at the end of path of oscillation
4. the velocity and acceleration at a distance 2cm from a centre of oscillation

Answer 5

1.T=1/f =1/50=0.02s
2. The acceleration at the middle point is zero
ii). A(max)=Aw²
w=2πf
w²=4π²f²
A(max)=0.04×4×3.14²×50²
=3944m/s
