What is the momentum of a bike with a mass of 18 kg traveling at 20m/s?​
liubo4ka [24]

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.

Mattie Evans drove 80 miles in the same amount of time that it took a turbopropeller plane to travel 400 miles. The speed of the
PtichkaEL [24]
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.

A different camera is selling for $7.50 off the regular price. It was marked down 15%. A student used the equation:
Debora [2.8K]

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.
