a) A cruise ship with a mass of 1.00×107 kg strikes a pier at a
speed of 0.750 m/s. It comes to rest 6.00 m later, damaging the
ship, the pier, and the tugboat captain’s finances. Calculate the
average force exerted on the pier using the concept of impulse.
(Hint: First calculate the time it took to bring the ship to
rest.)
b) The force of the water sloshing near the pier is enough to
push the ship back. After...

Suppose a large ship has a momentum of 1.55 × 109
kg⋅m/s.
(A) What is the mass of the large ship, in kilograms, if the
ship is moving at a speed of 45 km/h?
(B) How much larger is the ship’s momentum than the momentum of
a 1025-kg artillery shell fired at a speed of 290 m/s?
A person slaps her leg with her hand, bringing her hand to rest
in 250 ms from an initial speed of 3.95 m/s...

Suppose a spaceship has the mass of a typical ocean cruise ship,
then it can be assumed that it has a mass of 3.3 × 108
kg. Consider the kinetic energy required at 17 % of the speed of
light. If energy to get a spaceship to cruising speed is generated
using matter-antimatter annihilation, what mass of antimatter in kg
is required?
Hint: Matter-antimatter annihilation converts an entire mass of
matter and antimatter into pure energy with no loss.

A crate of mass 10.2 kg is pulled up a rough incline with an
initial speed of 1.56 m/s. The pulling force is 92 N parallel to
the incline, which makes an angle of 19.0° with the horizontal. The
coefficient of kinetic friction is 0.400, and the crate is pulled
5.04 m.
(a) How much work is done by the gravitational force on the
crate?
J
(b) Determine the increase in internal energy of the crate–incline
system owing to friction....

A 11.0-kg microwave oven is pushed 6.00 m up the sloping surface
of a loading ramp inclined at an angle of 35.9 ∘ above the
horizontal, by a constant force F⃗ with a magnitude 113 N and
acting parallel to the ramp. The coefficient of kinetic friction
between the oven and the ramp is 0.241.. 1 What is the work done on
the oven by the force F⃗ ? 2 What is the work done on the
oven by the...

Two tugboats pull a disabled container-ship loaded to 40,000
metric tons (40 million kg). Each tug exerts a constant force of
1.80×106 N , one at an angle 12.0 ∘ west of north, and
the other at an angle 12.0 ∘ east of north, as they pull the ship
0.880 km northward at constant 6 m/s.
A. What is the total work done to the ship by the two tugboat
Forces? in mega joules
B. What is the container-ship's Kinetic...

1. A 25 kg skydiver has a speed of 20 m/s at an altitude of 350
m above the ground. Determine the kinetic energy possessed by the
skydiver.
2. If a cruise ship travels 150 km to the south and then 250 km to
the west, what is the ship’s displacement from its starting
point?
3. A train is accelerating at a rate of 5 m/s . If its initial
velocity is 15 m/s, what is its speed after 10...

A 48.0-kg box is being pushed a distance of 6.04 m across the
floor by a force P whose magnitude is 162 N. The force P is
parallel to the displacement of the box. The coefficient of kinetic
friction is 0.206. Determine the work done on the box by (a) the
applied force, (b) the friction force, (c) the normal force, and
(d) by the force of gravity. Be sure to include the proper plus or
minus sign for the...

A meteoroid of mass = 565 kg has a speed of 91.0 m/s when 900 km
above the Earth. It is falling vertically (ignore air resistance)
and strikes a bed of sand in which it is brought to rest in 3.25 m.
(a) How much work does the force of gravity do on the meteoroid on
the way to the surface? Incorrect: Your answer is incorrect. GJ (b)
What is the speed of the meteoroid just before striking the sand?...
