Question

only need part c

(20%) Problem 5: A body of mass 1.8 kg and initial speed of 39 m/s collides with an initially resting body of mass 19 kg. The bodies stick together after the collision and continue moving (in the direction of the initially moving body). The motion takes place on a horizontal flat surface with negligible friction. 33% Part (a) Find the speed of the combined body immediately after the collision, in meters per second 3.375 Correct! 33% Part b) This collision is very inelastic. Calculate the loss of kinetic energy in joules, by subtracting the kinetic energy of the combined body immediately after the collision from the kinetic energy of the initially moving body immediately before the collision. Kiost- 1250.44 Kiost -1250 Correct! 33% Part (c) Find the increase in the internal energy, in joules, of the two bodies during the collision. Grade Summa Deductions Potential AUntermal- 1% 99%
