Answer:
78.4 kg
225.792 J
Explanation:
= Mass of person = 78.4 kg
= Mass of canister = 0.005 kg
= Initial Velocity of person = 0 m/s
= Initial Velocity of canister = 3.6 m/s
= Final Velocity of person = 2.4 m/s
= Final Velocity of canister = 1.2 m/s
In this system the linear momentum is conserved
The mass of the canister is 78.4 kg
Kinetic energy is given by
The energy lost in the collision is 225.792 J
Answer:360 kg m/s
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.
Brainlist please
15 × 2 = 30 ÷ 3 = 10. Hope this helps.
