Part D Corstants A 1030 kg sports car is moving weethound at 15.0 m son a evel roed when t oolides with a 6320 kg truck driving eaet on the same road at 12.0 m/s.The two vehicdes nemsin locked together after the collison Find he change in kinetic energy of the system of two vehicles for the stuations of partA AK- ? 1.38.10' Previsus Answers ReesE Answe Incorrect; Try Again; 17 attempts remaining Find the change in kinatie anergy of the system of two vhiclas for the stuationa of part C ax- 1.38 10 Submt

Explanation / Answer

A) v2x = ((1050 x (-15)) + (6320 x 12))/(1050 + 6320)

V2x = 8.15 m/s

C) delta KE = (0.5x7370x8.15^2) - (0.5x1050x15^2) - (0.5x6320x12^2) = - 3.28 x 10^5 J

D) delta KE = 0 - (0.5x1050x15^2)- (0.5x6320x2.5^2) = - 1.37 x 10^5 J
