Step-by-step explanation:
sorry no answer for 2
Answer:
1 A =
2 S = 12.5 m/s
Step-by-step explanation:
1
missing: A, acceleration
Given:
V1 initial speed = 0 m/s
V2 final speed = 20 m/s
T time = 5s
formula: A =
sol:
A =
A =
A =
2
Given:
missing: S, speed
W, wavelength = 50 m
F, frequenccy = 0.25 Hz
Hz = 1/s
Formula: S = W * F
S = 50m * 0.25Hz
S = 12.5m/s
