Document Summary

Phys 1010 6. 0: class test 3 on dec. 2, 2011. Time: 50 minutes; calculators & formulae provided at the end = only aid; total = 20 points: [5] a slowly moving car (mass 1200 kg, speed 25 km/h is hit directly from behind by an. The two vehicles stick together and emerge with some velocity right after the collision (before braking sets in; assume one-dimensional motion). Calculate how much kinetic energy is lost in the collision. Assuming a collision time of 0. 1 seconds nd the acceleration for both vehicles. 1: [5] two pucks of equal mass approach each other to collide at x = 0, y = 0. Puck 1 has a speed of 6 m/s, and moves along the x axis (at negative x before the collision). Puck 2 has a velocity of (3 i + 3 j) m/s (i. e. , approaches from negative x and y).
