Two balls of clay, with masses m1 = 0.49 kg and m2 = 0.47 kg, are thrown at each other and stick when they collide. mass 1 has a velocity v1 = 3.2i m/s and mass 2 has a velocity of v2 = 1.6j m/s. part (a) write an expression for the initial momentum of the system. p, in terms of the masses m1 and m2, the magnitudes of the velocities vi and v2, and the unit vectors i and j part (b) find the horizontal component of the final velocity vx, in meters per second, after the collision δ 33% part (c) find the vertical component of the final velocity vy, in meters per second, after the collision

Identify the type of synthetic material used in each object

An object of dimensions 50 cm x 40 cm x 0.20 cm has a mass 60g. find its density in g/cm3 and kg/ m3

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
