Optimus decides to throw Megatron down of a building at 5.0m/s. Megatron hits the ground at 32.0m/s
- How long does it take to hit the ground?
- How far does he fall?

Respuesta :

We have equation of motion v = u+at, where v is the final velocity, u is the initial velocity, t is the time taken and a is the acceleration.

Considering vertical motion of megatron

Here u = 0 m/s, a= 9.81 [tex]m/s^2[/tex] and v = 32 m/s

Substituting

     32 = 0+9.8*t

      t = 3.27 seconds

So it will take 3.27 seconds to reach ground.

Now considering horizontal motion of megatron

We have [tex]s =ut+\frac{1}{2} at^2[/tex], where s is the displacement, u is the initial velocity, t is the time taken and a is the acceleration.

In this case u = 5 m/s, t = 3.27 seconds, a = 0[tex]m/s^2[/tex]

Substituting

    [tex]s = 5*3.27+\frac{1}{2} *0*3.27^2\\ \\ s = 16.35 meter[/tex]

So Megatron falls 16.35 meter away from ground.
