How much internal energy is generated when a 20.0 g lead bullet, travelling at 7.00*10^2 m/s, comes to a stop as it strikes a metal plate

The internal energy generated  = 4900 J

Explanation:

Energy: Energy can be defined as the ability or the capacity to perform work. The S.I unit of Energy is Joules (J)

From the law of conservation of energy, the kinetic energy of the travelling bullet is converted to other forms of energy when it strike the metal plate.

E = 1/2mv² Equation 1

Given: m= 20 g = (20/100) kg = 0.02 kg, v = 7.00 × 10² m/s = 700 m/s

Substituting these values into equation 1

E = 1/2(0.02)(700)²

E = 0.01(490000)

E = 4900 J

Therefore, The internal energy generated  = 4900 J

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
