4.32.Set Up:The thrust of the engines produces an upward force on the rocket.Solve: (a)The free-body diagram for the rocket is given in Figure 4.32a.is the weight of the rocket and astronaut.Figure 4.32(b)The free-body diagram for the astronaut is given in Figure 4.32b. The astronaut is in contact with the floor, andthis surface exerts an upward force The thrust acts on the rocket, not on the astronaut.4.33.Set Up:The suitcase is in contact with the floor and this surface exerts an upward force and a horizontalforce that is directed opposite to the motion of the suitcase.Solve:The free-body diagram for the suitcase is shown in Figure 4.33.Figure 4.334.34.Set Up:There is a friction force between the floor and the bottom crate and a different friction force betweenthe two crates. Call the bottom crate Aand the top crate
