This is a physics problem.
The law is that the momentum is preserved: total momentum before collsion = total momentum after collision
Momentum before collision = 80 kg.m/s - 100 kg.m/s = -20 kg.m/s
Then answer is b. - 20 kg.m/s
Answer:

Answer:
The dimensions of rectangular fence are 14 feet and 20 feet.
Step-by-step explanation:
We are given the following in the question:
Length of rectangular fence = 14 feet
Width of fence = (14+x) feet
Area of rectangular field = 280 square feet
Area of rectangular field =
Putting the values, we get,
Thus, the dimensions of rectangular fence are 14 feet and 20 feet.
Answer:
2 x+3 y and 3 x+ 2 y
Step-by-step explanation:
Let x represents the number of roast beef and y represents the number of turkey sandwiches.
Let r and t represent cost of the roast beef and sandwich.
Platter A:
Platter A has 2 roast beef and 3 turkey sandwiches. So, equation is 2 x+3 y.
Total cost of the platter = 2 r x+3 t y
Platter B:
Platter B has 3 roast beef and 2 turkey sandwiches. So, equation is 3 x+2 y.
Total cost of the platter = 3 r x+2 t y
So, the two equations are 2 x+3 y and 3 x+ 2 y.
