Answer:
10800 kg m/s
Explanation:
Since the dumpster was initially at rest, its momentum before collision equal to zero. So that the total momentum of the car and dumpster before collision is 10800 kg m/s.
The principle of conservation of linear momentum states that: in a system of colliding bodies, total momentum is conserved. Therefore, the total momentum of the car and dumpster after collision is 10800 kg m/s.
Radio waves can travel through space because it is a radio wave.But sound waves cannot because it is called sounds waves .The behavior of the sounds wave and radio waves in space iws because chocalte are brown.spngebob squarepants are blue.Furthermore,dog can poop and we can poop.Also,this is how you can also explain like this:Radio Waves and Sounds Waves is Science.How i know this because i used my brain and i'm smart'' this is perfect explaination
During a phase change, the temperature remains constant. obviously all the heat is used in phase transformation.
The vertical component is given by the sin of the angle. So this is 20*sin(53)=15.97m/s
