Two cars, one of mass 1300 kg, and the second of mass 2400 kg, are moving at right angles to each other when they collide and st
Margarita [4]

To solve this problem we will apply the momentum conservation theorem, that is, the initial momentum of the bodies must be the same final momentum of the bodies. The value that will be obtained will be a vector value of the final speed of which the magnitude will be found later. Our values are given as,

m_1 = 1300kg

m_2 = 2400kg

u_1 = 12m/s i

u_2 = 18m/s j

Using conservation of momentum,

m_1u_1+m_2u_2 = (m_1+m_2)v_f

1300*12i-2400*18j = (1300+2400)v_f

Solving for v_f

v_f = 4.2162i-11.6756j

Using the properties of vectors to find the magnitude we have,

|v| = \sqrt{(4.2162^2)+(-11.6756)^2}

|v| = 12.4135m/s

Therefore the magnitude of the velocity of the wreckage of the two cars immediately after the collision is 12.4135m/s

What is the potential energy in J of a bungee jumper standing on a 0.109 km bridge that weighs 85 kg?
KatRina [158]

Considering the definition of potential energy, the potential energy of the bungee jumper is 90,889.65 J.

<h3>Potential energy</h3>

Potential energy is the energy that measures the ability of a system to do work based on its position. In other words, this is the energy that a body located at a certain height above the ground has.

Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the strength of gravity.

So for an object with mass m, at height h, the expression applied to the gravitational energy of the object is:

Ep= m×g×h

Where:

  • Ep is the potential energy in joules (J).
  • m is the mass in kilograms (kg).
  • h is the height in meters (m).
  • g is the acceleration of fall in m/s² (approximately 9.81 m/s²).

<h3>Potential energy in this case</h3>

In this case, you know:

  • m= 85 kg
  • g= 9.81 m/s²
  • h= 0.109 km= 109 m (being 1 km= 1000 m)

Replacing in the definition of potential energy:

Ep= 85 kg × 9.81 m/s² × 109 m

Solving:

<u><em>Ep= 90,889.65 J</em></u>

Finally, the potential energy of the bungee jumper is 90,889.65 J.
