A mass m1= 3kg slides down slippery ramp, reaching a speed v=9 m/s at the bottom. After reaching the level ground m1 collides with mass m2= 4kg at bottom, sticking together in a perfectly inelastic collision. The combined mass then slides over a floor, finally coming to rest after travelling a horizontal distance x= 6m. a.) What was the height of the ramp, assuming that m1 started from rest? b.) How fast were the combined masses m1 and m2 moving after sticking together?

Two objects collide head-on (see figure below). The first object is moving with an initial speed of v1i = 8.09 m/s and the second object is moving with an initial speed of v2i = 10.00 m/s. Assuming the collision is elastic, m1 = 5.06 kg, and m2 = 6.18 kg, determine the final velocity of each object. (Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the nature of this problem, do not use rounded intermediate values in your calculations) v1f = m/s v2f = m/s
