A ship has a top speed of 3.0 m/s in calm water. The
current of the ocean
tends to push the boat at 2.0 m/s on a bearing of due South.
What will be the
net velocity of the ship if the captain points his ship on a
bearing of 55
North or West and applies full power?
An airplane is 50,000 m above an observer and 2.1 km to the
west of them and
1.5 km to the north of you. Determine the angle to the plane
in the x y axis
and the total distance to the plane from you. Choose the
x-axis east, y axis
north, and z axis up.
A bullet is fired from at a shooting range. The bullet hits the
0.32 seconds. How far did it travel horizontally and
vertically in this time if
it was fired at a velocity of 1100 m/s?
A not so brilliant physics students wants to jump from their
apartment window to the swimming pool below. The problem is
the base of the
apartment is 8.00 meters from the pools edge. If the window
is 20.0 meters
high, how fast does the student have to be running
horizontally to make sure
they make it to the pools edge?
If a 1500 kg car stopped from an in 5.6 seconds with an applied
5000 N, how fast was it initially traveling?
If the acceleration due to gravity on the Moon is 1/6 that what
is on the
Earth, what would a 100 kg man weight on the Moon? If a
person tried to simulate
this gravity in an elevator, how fast would it have to
accelerate and in which
A 7.93 kg box is pulled along a horizontal surface by a force
Pof 84.0 N applied at a 47.0
oangle. If the
coefficient of kinetic friction is 0.35, what is the
acceleration of the box?
If a car is traveling at 50 m/s and then stops over 300 meters
sliding), what is the coefficient of kinetic friction between
the tires of the
car and the road?
