What energy went into the deformation of two colliding balls with masses m1 = m2 = 4 kg if they were moving towards each other with velocities v1 = 3 m / s, v2 = 8 m / s, and the impact was direct inelastic?
Given:
m1 = m2 = 4 kg
v1 = 3 m / s
v2 = 8 m / s
Find: ΔE -?
Decision:
ΔЕ = m1m2 (V1 + V2) ^ 2/2 (m1 + m2)
ΔE = (4 * 4) * (3 + 8) ^ 2/2 * (4 + 4) = 121 J
Answer. E = 121 J
