<span>A plane flies along a straight line path after taking off, and it ends up 210 km farther east and 90.0 km farther north, relative to where it started. we should use Pythagoras theorem for this. distance^2= 210^2 + 90^2.=228.47km, when rounding off this would comes around 230 km</span>

Answer:

The plane's displacement is 228.47 km.

Explanation:

It is given that,

Distance covered in east direction is 210 km and distance covered in north direction is 90 km. Let d is the plane's displacement. It is equal to the shortest path covered by the particle.

d=\sqrt{d_1^2+d_2^2}

d=\sqrt{(210)^2+(90)^2}

d = 228.47 km

So, the plane's displacement is 228.47 km. Hence, this is the required solution.

Answer:

536.56 m/s

Explanation:

We'll begin by calculating the momentum of the Porsche. This can be obtained as follow:

Mass (m) of Porsche = 1361 kg

Velocity (v) of Porsche = 26.82 m/s

Momentum of Porsche =?

Momentum = mass × velocity

Momentum = 1361 × 26.82

Momentum of Porsche = 36502.02 Kgm/s

Finally, we shall determine the velocity you need to be running with in order to have the same momentum as the Porsche. This can be obtained as follow:

Your Mass = 68.03 kg

Your Momentum = Momentum of Porsche = 36502.02 Kgm/s

Your velocity =?

Momentum = mass × velocity

36502.02 = 68.03 × velocity

Divide both side by 68.03

Velocity = 36502.02 / 68.03

Velocity = 536.56 m/s

Thus you must be running with a speed of 536.56 m/s in order to have the same momentum as Porsche.

what is the maximum speed of a 34-g object bouncing on a spring (k=78.1 N/m) with an amplitude of 3.5-cm?
Vika [28.1K]

Answer:

The maximum speed of the mass is 1.67 m/s.  

Explanation:

We have,

Mass of object is 34 g or 0.034 kg

Spring constant of the spring is 78.1 N/m

Amplitude attained by the object is 3.5 cm or 0.035 m

It is required to find the maximum speed of the object in this spring mass system. The maximum speed is given by :

v=A\omega

\omega=\sqrt{\dfrac{k}{m}}

v=A\sqrt{\dfrac{k}{m}}

Plugging all the values in above formula,

v=0.035\times \sqrt{\dfrac{78.1}{0.034}}\\\\v=1.67\ m/s

So, the maximum speed of the mass is 1.67 m/s.

A person walks 30m due north, then 50m at 35 degrees. Find their total displacement.
Harman [31]
Using the cosine rule (a^2 = b^2 + c^2 - 2bc cos A), we can work out the displacement:
Displacement = a
b = 30
c = 50
A = 180 - 35 = 145 degrees.

a^2= 900 + 2500 -1500*-0.81915...
      = 3400 + 1228.728...
      = 4628.72...
a = 68.034...
   = 68.0m (to 3s.f.).

To work out the angle from starting place, use another configuration of the cosine rule: 
cos(C)= \frac{a^{2} +b^{2}-  c^{2}  }{2ab}:
cos (C)= \frac{4628.72...+900-2500}{2*68*30}
           = 3028.7.../4080
           = 0.7423...
C = 42.069... degrees
   = 042 bearing
