Answer:
mv-mu
Explanation:
momentum is the mass by velocity of an object. change in momentum means there was an initial momentum and a final momentum. V represents the final momentum and U represents the initial momentum. So minus the momentum values. (Final momentum (mv) minis initial momentum (mu)
Answer:
The work done on the suitcase is, W = 1691 J
Explanation:
Given data,
The force on the suitcase is, F = 89 N
The distance Russell dragged the suitcase, S = 19 m
The work done on the suitcase by Russell is equal to the work done on the suitcase to overcome the friction
The work done on the suitcase by Russell is given by the formula
W = F · S
Substituting the given values,
W = 89 N x 19 m
W = 1691 J
Hence, the work done on the suitcase is, W = 1691 J
