It is true for n=2, 3 and 4
Answer:
360 kg m/s
Step-by-step explanation:
Momentum refers to an object's quantity of motion.
Formula for Momentum: p=mv
p = refers to the momentum
m = refers to the object's mass (this is represented by the unit kg or kilogram)
v = this refers to the object's velocity (this is represented by the unit m/s or meter per second)
So, given that the bike has a mass of 18 kg and is traveling at 20 m/s, then you can already get the momentum by multiplying both of these values.
p = the bike's momentum (what is being asked here)
m = 18 kg
v = 20 m/s
Thus, p = 18kg × 20 m/s = 360 kg m/s
The bike's momentum is 360 kg m/s.
There is not a real way to justify this, but I saw first that 400-80 equals 320 which is double 160. This made me think that the period of time during this was 2 hours. The car drove 80 miles in two hours and the plane flew 400 miles in 2 hours. The period for one hour would be 40 mph for the car and 200 mph for the plane. 200-40=160. I have no idea how to prove it though and I’m hoping you can go backwards.
Answer:
The original price is $50. The student's mistake in the equation is that he should have done 7.5/0.15
The student should not have multiplied, instead divided. He also didn't put 15 in a decimal form, which would have messed the whole equation up.
the answer i got is 13.125
idk how this would make sense (no pun intended)
