a. Place the crate on top of the ramp with the angle at
20o. Draw a free body diagram showing all the
forces and their components.
b. If the crate does not go down the ramp, which two forces are
responsible for keeping the ramp at rest and preventing it from
sliding down?
c. Slowly increase the angle until the block JUST starts to
move. What is the angle when the block JUST moves?
d. For the angle when the block JUST...

11. A car of mass m is on an icy driveway inclined at an angle 0 as shown above (a) Draw the free-body diagram for the car. (b) Write down Newton's 2ad law for the car along the two axes in your free body diagram. (c) Find the acceleration of the car (in terms of 0 and g), assuming that the driveway is frictionless. (d) Suppose the car is released from rest at the top of the incline and the...

this example shows the uses of co-coordinate axes,
my question is why is it that we can substitute T for w2 for
the second equation , won t it be wrong since we are using two
different sets of axes
does it have something to do with expressing newtons second
law in terms of magnittude?
can someone explain more about the uses of co-coordinate axes
and when is it not apprioriate not to use it?

Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....

ements Constants ents SOLUTION We will look at an example where several forces are acting on an object, but in this case the forces are not all along the same axis. As shown in (Figure 1), a car engine with weight to hangs from a chain that is linked at point to two other chains, one fastened to the ceiling and the other to the wall. Find the tension in each of the three chains, assuming that is given and...
