Exercise 23 through 27 describe a situation. For each, identify all forces acting on the object and draw a free-body diagram of the object.
23. A cat is sitting on a window sill.
24. An ice hockey puck glides across frictionless ice.
25. Your physics textbook is sliding across the table.
26. A steel beam, suspended by a single cable, is being lowered by a crane at a steadily decreasing speed.
27. A jet plane is accelerating down the runway during takeoff. Friction is negligible, but air resistance is not.

- 13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…arrow_forwardNo chatgpt pls will upvotearrow_forwarda cubic foot of argon at 20 degrees celsius is isentropically compressed from 1 atm to 425 KPa.
