How do you think electricity was discovered
sasho [114]
Italian physicist Alessandro Volta discovered that particular chemical reactions could produce electricity, and in 1800 he constructed the voltaic pile (an early electric battery) that produced a steady electric current, and so he was the first person to create a steady flow of electrical charge.

A 91.5 kg football player running east at 2.73 m/s tackles a 63.5 kg player running east at 3.09 m/s. what is their velocity aft
pentagon [3]

Answer:

2.877 m/s

Explanation:

According to the laws of conservation of linear momentum,

the momentum of the moving objects before impact is equal to the momentum of the objects after impact (Assuming no external forces were applied)

Let both players are tackled and moving in V velocity

  • M and m - masses of the players
  • U and  u -  velocities of them respectively (both velocities are towards east direction )

momentum before impact = momentum after impact

                          →MU + →mu  = →(M+ m )v

 91.5  * 2.73 + 63.5 * 3.09 =  (91.5 + 63.5) * V

                                       →V = 2.877 m/s (To East)
