kg m/s hits a nomentum of the ball is(5 wall and bounces straight back with the sam B. +4.0 kg-m/s C8.0kgm/s. Questions 2, 3; A 6.0 kg object moving north at a speed of 3.0 m/s, collides with a 4.0kg objot moving sous D.-8.0kgm/s Enone of the with speed of 6.0 m/s. On collision, the two objects stick togetber and move s one cbject 2. The magnitude of the sum of the linear momentum of the two objects just aher the collision is the magnitude of the sum of the linear momentum of the two objects just before the collision.1S A. equal to B. more than C.less than D. nons of thee 3. The total kinetic energy of the two objects just after the collision is two objects just before the collision.(5 A. equal to the otal kinetic energy of the D. none of thes B. more than C. less than 4. The force versus time graph is shown for a 35 g ball on impact with a nacket Each grid on the boiaotal scale is equal to 1. If the initial velocity of the ball is 10 m/s, find the final velocity 7 F (N) 10 5. An object initially at rest explodes into three fragments. The momentum vectors of two of the fragments are. shown. Find and draw the momentum vector py of the third fragment.(8) 10 t (ms) 0

Consen Since mom ₂ T (A) equal to] since momentum is conserved. ₂ (C) Less than sine energy is lust. Impulse - Area of the graphe = [₂ x 4x10) + (luxu) + (²x2x10) ] 10 m3 to x103) NG Also Inputse = Dpa mlufari) – 70 x103 .. & (35x10 ) Cuc - 10) = to xlo & f = 12 m/s) (5). The not momention must be o. Therefore, to convert ms. P2 23
