After a 70 kg person steps from a boat onto the shore, the boat moves away with a speed of 0.7 m/s with respect to the shore. If the same person steps from the shore onto the boat, the person and the boat move away from the shore with the speed of 0.5 m/s. Assume that the initial speed of the person with respect to the shore is the same in both cases and that the person is moving in a horizontal direction. (a) Draw impulse-momentum bar charts for both situations. (b) Determine the mass of the boat and the speed of the person.
After a 90-kg person steps from a boat onto the shore, the boat moves away with a speed of 0.70 m/s with respect to the shore. If the same person steps from the shore onto the boat, the person and the boat move away from the shore with the speed of 0.50 m/s. Assume that the initial speed of the person with respect to the shore is the same in both cases and that the person is moving in a horizontal direction. Determine the Mass of the boat and the speed of the person.
The parameters of instantaneous speed, altitude, net engine thrust and wind speed are given for the above 5000 kg aircraft, which accelerates and moves at a fixed altitude, while leaving a load of 150 kg.
In case the air friction is neglected, calculate the distance between the load and the aircraft while falling to the ground.
