We have the equation of motion
, where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.
Here displacement = 135 m, Initial velocity = 0 m/s, acceleration = 9.81
Substituting

A box falls out of a stationary helicopter hovering 135 m above the ground will take 5.25 seconds to reach the ground.
Answer:
24.4 m
Explanation:
first we have to calculate how long the cat will be in the air, in vertical direction this is free fall from 4m (poor cat, hope he survived) with acceleration of g=9.81 m/s^2
time = sqrt ( 2 * height / g)
time = sqrt (2 * 4 / 9.81)
time = 0,903 s
then we know his horizontal flight was 22 m long, so ve can calculate verical speed
speed = length / time
speed = 22 m / 0,903 s
speed = 24.363 m
as you are asked to give 3 significant numbers answer is 24,4 m

I'm sure its transverse, longitudinal and surface
Explanation:
sorry if I'm wrong
A) they have no effect on air temperature over land on the coast is False
Explanation:
- warm and cold ocean currents can influence the coastal areas only when the air is blown into the land from the sea.
- the temperature over the land increases when warm ocean currents heat the air above the ocean.
- the temperature over the land decreases when cold ocean currents cool the air above the ocean and can bring colder winds to the coastal regions.
- so, ocean currents play a major role in regulating the air temperature over land on the coastal region.
