Question

Could you please please solve both questions, I would really appreciate it.

1. An object is undergoing SHM with period 0.350 s and amplitude 6.30 cm . At t=0 the object is instantaneously at rest at x= 6.30 cm .

  Calculate the time it takes the object to go from x= 6.30 cm to x= -1.60 cm .

2. When a 0.850-kg mass oscillates on an ideal spring, the frequency is 1.35 Hz .

a) What will the frequency be if 0.190 kg are added to the original mass? Try to solve this problem without finding the force constant of the spring.

Express your answer with the appropriate units.

b) What will the frequency be if 0.190 kg are subtracted from the original mass? Try to solve this problem without finding the force constant of the spring.

Express your answer with the appropriate units.
