Describe how engineers designed a parachute to create the forces needed to slow down the falling person.

Physics

Answer:

Due to the resistance of air, a drag force acts on a falling body (parachute) to slow down its motion. Without air resistance, or drag, objects would continue to increase speed until they hit the ground. The larger the object, the greater its air resistance. Parachutes use a large canopy to increase air resistance. Also, Once the parachute is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward. An upward net force on a downward falling object would cause that object to slow down. The skydiver thus slows down.

TRUE or FALSE: During a collision between objects of different mass, there is a greater force applied to the less massive object

ddd [48]

If they are moving at the same speed then it would be true because the larger object would have more mass and would have more momentum then the smaller object that has less mass! Hope this helps!

If an object is projected upward from ground level with an initial velocity of 160 ft per sec, then its height in feet after t

sesenic [268]

Answer:

Time will be 5 sec

And maximum height will be 1200 feet

Explanation:

We have given that initial velocity of the object u = 160 ft/sec'

Function of height $s(t)=-16t^2+160t$

Take derivative of the distance

We know that first derivative of distance is velocity

So $v(t)=-32t+160$

At maximum height we know that velocity is zero

So $-32t+160=0$

t = 5 sec

So it will take 5 sec to reach maximum height

Now maximum height will occur at t = 5 sec

So maximum height = $16\times 5^2+160\times 5=1200feet$

Which best describes a tsunami?

eduard

Answer:

A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water.
