An aeroplane accelerates from rest at a rate of 25m/s² for 3 s .calculate final velocity​

Physics

Reptile [31]3 years ago
8 0

Answer:

<em>The final speed is 75 m/s</em>

Explanation:

<u>Constant Acceleration Motion</u>

It's a type of motion in which the velocity of an object changes uniformly in time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

v_f=v_o+at

The airplane comes from rest (vo=0) accelerating at a=25 m/s^2 for t=3 s.

The final speed is:

v_f=0+25~m/s^2\cdot 3~s

v_f=75~m/s

The final speed is 75 m/s

As soon as parachute of a falling soldier opens, how will the accleration change?​
WITCHER [35]

Answer:

The acceleration will become zero

Explanation:

When the parachute of a falling soldier is opened the wide surface area decreases his velocity. This also translates to the drag force acting on the fallen soldier

The acceleration will become zero when the velocity of the fallen soldier is constant. This principle is the reason the parachute is used for safety reasons .

a car that is moving in a straight line has an acceleration of 8.0 m/s/s for 4.0 seconds. which one of the following is true of
Nuetrik [128]

Answer:

32 ms

Explanation:

v=32ms.

Explanation:

I will assume that you mean that the acceleration is 8.0 ms2, as 8.0ms is a value for velocity, not acceleration.

Here, we use the formula v=u+at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is time. Let's substitute values, then:

v=u+at,

v=0+8.0⋅4.0

v=32,

v=32ms.

Hope it Helps! :D .
