Can you please show steps! Thank you

1-3. As the bob of a pendulum swings towards its lowest point, 1) its angular frequency 2) its acceleration 3) its speed: A. increases B. decreases C. does not change 4. A spring-mass system is undergoing a SHRM of amplitude 2.0 cm and angular frequency 10.0 rad/s. The acceleration of the mass as is pass through equilibrium point is (in m/s^2) A. 0 B. 0.20 C. 2.0 D. 31.4 E. 62.8 5. When a mass attached to a spring is released from rest at 2.0 cm from equilibrium position, it oscillates with frequency f. If the same mass were instead released from rest 4.0 cm from equilibrium position, it oscillates with frequency A.f/4 B. 2f C. 4f D. f E.f/2

Explanation / Answer

1) does not change

2) decreases

3) increases

+++++++++++
4)a = -w^2*x

here at equilibrium x = 0

a = 0

option A
++++++++++++++

5) f = (1/2pi)*sqrt(k/m)

f does not depend on amplitude

f

option D
