Answer:
Velocity = 0.5 m/s South (A)
Explanation:
You need to determine the average rate of velocity.
The equation you will use is velocity = displacement/time
The displacement is 30m South.
The time is 60 seconds.
Plug into the equation Velocity = 30m South/60 s
Velocity = 0.5 m/s South
50 +50 =100 Since it’s sitting on a 50m cliff that’s high with a mass of 50 kg it would be adding because once it goes down it’s adding speed
Answer:
Explanation:
Distance travelled by wave = 8 x 2 = 16 m
Time taken = 4 s
velocity of pulse wave = distance / time
= 16 m / 4 s
= 4 m/s
