Question

PLEASE don't just guess.. it's dishonest.

Two identical carts roll down hills and stick together in two different situations

1.Which one of the following statements is truejust beforethe carts collide in the two cases?

a.The kinetic energy of the system is zero in case (ii)

b.The kinetic energy of the system is greater

in case (i) than in case (ii)

c.The kinetic energy of the system is the same in both cases

d.The momentum of the system is greater

in case (ii) than in case (i)

e.The momentum of the system is the same in both cases

f.More than one of these statements are true

2.Referring to the figure in the previous page, which of the following statements is truejust afterthe carts collide in the two cases?

a.The kinetic energy of the system is greater

in case (ii) than in case (i)

b.The kinetic energy of the system is the same in both cases

c.The momentum of the system is greater

in case (ii) than in case (i)

d.The momentum of the system is non-zero in case (i) while it is zero in case (ii)

e.The momentum of the system is the same in both cases

f.More than one of these statements are true
