+55 A student weighing 65 kg moving at 1.5 m/s runs into a student at rest weighing 45 kg. Rhe heavier student continues forward with a speed of 0.5 m/s after the crash. How fast is the smaller student moving after the crash? (in m/s)
Please help with this problem. Thanks!
+37155 I think this is a conservation of momentum type problem
Momentum before crash = momentum after crash
65 kg x 1.5 m/s = 65 kg x .5m/s + 45 kg x ? m/s
97.5 = 32.5 + 45 x?
?= 1.44 m/s
