Problem 28.
28.
- (a) Just before the player leaves the ground, the forces on the player are his weight and the floor pushing up on the player. If the player jumps straight up, then the force of the floor will be straight up – a normal force. See the first diagram. In this case, while touching the floor. FN > mg.
- (b) While the player is in the air. the only force on the player is their weight. See the second diagram.

Three mountain climbers who are roped together in a line
are ascending an icefield inclined at 31.0° to the horizontal
(Fig. 4-69). The last climber slips, pulling the second
climber off his feet. The first climber is able to hold them
both. If each climber has a mass of 75 kg, calculate the ten-
sion in each of the two sections of rope between the three
climbers. Ignore friction between the ice and the fallen
climbers.

A box rests on the (frictionless) bed of a truck. The truck
driver starts the truck and accelerates forward. The box
immediately starts to slide toward the rear of the truck bed.
Discuss the motion of the box, in terms of Newton's laws, as
seen (a) by Mary standing on the ground beside the truck,
and (b) by Chris who is riding on the truck (Fig. 4–35).

A train locomotive is pulling two cars of the same mass behind it, Fig. 4–51. Determine the ratio of the tension in the coupling (think of it as a cord) between the locomotive and the first car (FT1), to that between the first car and the second car (FT2), for any nonzero acceleration of the train. You need to draw a FBD for each car.

- Two rock climbers, Jim and Karen, use safety ropes of simi- lar length. Karen's rope is more elastic, called a dynamic rope by climbers. Jim has a static rope, not recommended for safety purposes in pro climbing. (a) Karen (Fig. 4–71) falls freely about 2.0 m and then the rope stops her over a distance of 1.0 m. Estimate how large a force (assume constant) she will feel from the rope. (Express the result in multiples of her weight.) (b) In a similar fall, Jim's rope stretches by only 30 cm. How many times his weight will the rope pull on him? Which climber is more likely to be hurt?
