A mass of 1 kg is suspended from a spring of force constant 400 N , executing SHM total energy of the body is 2 J , then maximum acceleration of the spring will be
Options
- A4 ~m / s ^2
- B40 ~m / s ^2
- C200 ~m / s ^2
- D400 ~m / s ^2
Correct answer
B. 40 ~m / s ^2
Step-by-step solution
T=2 m R =2 1 400 = 2 20 Frequency n= 20 2 =2 n=2 20 2 =20 Total energy aligned & E= 1 2 m ^2 r^2 & 2= 1 2 1 400 r^2 aligned gathered r= 1 10 ~m Acceleration = ^2 r=400 1 10 =40 ~m / s ^2 gathered
