1 Physics 30 Momentum 2D Practice 1.19 m/s, 20º S of E
2 2. A 15.0 kg object is moving east at a velocity of 7.0 m/s when it collides with a 10.0 kg stationary object. After the collision the 15.0 kg object is travelling at a velocity of 4.2 m/s, 20.0º S of E. What is the velocity of the 10.0 kg object after the collision? (5.1 m/s, 25º N of E) 3. An object explodes into three equal masses. One mass moves east at 15.0 m/s. A second mass moves at a velocity of 10.0 m/s, 45.0º S of E. What is the velocity of the third mass? (23.2 m/s, 17.8º N of W)
3 4. A 50.0 kg object is moving east at an unknown velocity when it collides with a 60.0 kg stationary object. After the collision, the 50.0 kg object is travelling at a velocity of 6.0 m/s 50.0° N of E and the 60.0 kg object is travelling at a velocity of 6.3 m/s 38° S of E. Find the velocity of the 50.0 kg object before the collision. (9.8 m/s East)
4 Answer 232
5 6. 21º S of E
