Chapter 4, Problem 29P
|| A factory worker pushes horizontally on a 250 N crate with a force of 75 N on a horizontal rough floor. A 135 N crate rests on top of the one being pushed and moves along with it. Make a free-body diagram of each crate if the friction force exerted by the floor is less than the worker’s push.

|| It's a snowy day and you're pulling a friend along a level road on a sled. You've both
been taking physics, so she asks what you think the coefficient of friction between the sled
and the snow is. You've been walking at a steady 1.5 m/s, and the rope pulls up on the
sled at a 30° angle. You estimate that the mass of the sled, with your friend on it, is 60 kg
and that you're pulling with a force of 75 N. What answer will you give?
|(1) Two objects are connected by a light string that passes over a
frictionless pulley as shown in Figure 2.

55.0°. (a) Draw free-body diagrams of both objects. Find
(b) the magnitude of the accel eration of the objects, (c) the ten-
sion in the string, and (d) the speed of each object 2.00 s after
it is released from rest.
