Answer:
17 cm/s
Explanation:
Amplitude is the half of the distance between the two extreme points
So, amplitude, A = 27 / 2 = 13.5 mm
Timeperiod, T = 1/2 second = 0.5 second
Maximum speed, v = A x ω
Where, ω is the angular frequency
ω = 2π / T = 2 x 3.14 / 0.5 = 12.56 rad/s
v = 13.5 x 12.56 mm/s
v = 169.56 mm /s
v = 16.96 cm/s
v = 17 cm/s
Answer:
0.027m/s
Explanation:
The speed of a body is the distance travelled with respect to time taken.
Mathematically;
Speed = Distance/time
Distance = 27.0mm
Time = 1.00secs
Since 1000mm = 1m
27mm = (27/1000)m
27mm = 0.027m
Speed = 0.027/1.00
Speed of the pendulum = 0.027m/s
