Answer:
A perfectly elastic collision conserves momentum and kinetic energy..
<span>Map Key or Legend. A map key or legend is included with a map to unlock it. It gives you the information needed for the map to make sense. Maps often use symbols or colors to represent things, and the map key explains what they mean</span>
I think the correct answer from the choices listed above is option C. The formula that would represent the speed of the Toyota would be <span>T+10 mph= 60 mph. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
To solve this problem we will begin by finding the force on each of the elements. For this it will be necessary to obtain the mass, which can be related to density and volume. Finally, by balancing forces it will be possible to obtain the final value of the maximum mass that can be lifted.
By Newton's second law we have,

Here,
g = Gravitational acceleration
m = mass
At the same time mass can be described as,


Therefore the Force 1 is,



Applying the same concepto but for the second mass we have,



Now by equilibrium we have,




Therefore the maximum mass lift by balloon is
