Answer:
A = 1m
ranges from -1m to 1m
period = 0.5 s
frequency = 2Hz
Explanation:
Let the origin be the resting point of the mass. As the mass is pulled down to -1m and oscillates between -1m and 1m.
The amplitude A is 1m
The full range of vertical motion is between -1m and 1m
The period is 0.5s as it's the time it takes to complete a full circle
The frequency is the period inverted, which is 2
