I would say all of them, because when making an observation you use, sight,sound,taste,touch, and smell
displacement of the plane is given as
time taken by the plane
now the velocity is given as
so the velocity of airplane is 399 mi/h towards South West
Answer:
36 km/h
Explanation:
The total velocity is the sum of the two velocities that add to the movement of the boat.
Since the wind pushes the boat at 21 km/h and the current that runs in the direction of the movent of the boat is 15 km/h, the total velocity at wich the boat moves is:
21km/h + 15 km/h = 36 km/h
Answer:
9 kg
Explanation:
Momentum is mass times velocity.
p = mv
36 kgm/s = m (4 m/s)
m = 9 kg
<span>I think it would kinetic energy which is the same as potentail energy</span>
