A dad and his kid are riding bumper cars at the amusement park.  The dad and his car weigh 200 kg, combined, and are travelling at 1 m/s at the time of collision.  The kid and their car weigh 125 kg, and are traveling -2 m/s at the time of collision. Step 1. This collision is Elastic.
Step 2:  Before the collision, what is the momentum of...
Dad   kg * m/s
Kid   kg * m/s  
Step 3: After the collision, what is the momentum of...
Dad   kg * m/s
Kid   kg * m/s    
Step 4: Using v = p/m, what is the final velocity of...
Dad   m/s
Kid   m/s​

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example
