Which has more momentum, a #5# #kg# object moving at #16# #ms^-1# or a #5# #kg# object moving at #20# #ms^-1#?

Answer:

Momentum is given by #p=mv#, momentum equals mass times velocity. In this case, the mass is constant, so the object with the greater velocity has the greater momentum.

Explanation:

Just to check, we can calculate the momentum for each object.

For the first object:

#p=mv=5*16=80# #kgms^-1#

For the second object:

#p=mv=5*20=100# #kgms^-1#
