Consider the motion towards right as positive and motion towards left as negative.
m₁ = mass of the cart moving to right = 0.500 kg
v₁ = initial velocity before collision of the cart moving towards right = 2.2 m/s
m₂ = mass of cart moving to left = 0.800 kg
v₂ = initial velocity before collision of the cart moving towards left = - 1.1 m/s
initial momentum of the system of carts before the collision is given as
P₁ = m₁ v₁ + m₂ v₂
P₁ = (0.500) (2.2) + (0.800) (- 1.1)
P₁ = 0.22 kg m/s
P₂ = momentum of system of carts after collision
As per conservation of momentum,
Momentum of system of carts after collision = Momentum of system of carts before collision
P₂ = P₁
P₂ = 0.22 kg m/s
Answer:
D. the amount of water placed in jars
Explanation:
it was the same for all of the jars at the beginning
Answer:0.5
Explanation:
Given
Piece of taffy slams in to sticks to another identical piece and stuck into it.
Let m be the mass of taffy and u be the initial velocity of taffy and v be the final velocity of system.
Conserving momentum
Initial kinetic energy
Final Kinetic Energy
change in kinetic energy 
change in kinetic energy will contribute in heat energy
thus fraction of kinetic energy converted in to heat 
Answer:18.29m/s^2
Explanation:
Centripetal acceleration=(velocity)^2÷radius
Centripetal acceleration=(32^2)/56
Centripetal acceleration=(32×32)/56
Centripetal acceleration=1024/56
Centripetal acceleration=18.29m/s^2
