Per:
1.
A child is pulling a wagon with toys of varying masses in it. The combined mass of the wagon and the
toys is initially 10 kg. The initial velocity is 0.89 m/s.
Read each of the sentences that describe a change to the wagon and/or toys. For each scenario, circle
whether the kinetic energy increases, decreases, or stays the same.
A. The child increases the velocity of the wagon to 0.92 m/s.
KE increases
KE decreases
KE remains the same
B. The child removes a toy bear of mass 0.23 kg and the velocity remains the same.
KE increases
KE decreases
KE remains the same
C. The velocity of the wagon decreases to 0.27 m/s.
KE increases
KE decreases
KE remains the same
D. The child turns the wagon around, and its new velocity is -1.12 m/s.
KE increases
KE decreases
KE remains the same
E. The child adds 2.1 kg of rocks to the wagon and the velocity decreases to 0.71 m/s.
KE increases
KE decreases
KE remains the same
F. The child adds toys until the total mass is 11.6 kg, and the velocity changes to 0.85 m/s.
KE decreases
KE remains the same
KE increases
