Phys201 Exam 2 LONCAPA Questions
And Answers With Verified Solutions
Already Passed Latest Updated 2025
A hydraulic jack is made with a small piston 1.3 cm in diameter that is used to
move a large piston 6.2 cm in diameter. If a man can exert a force of 380 N on
the small piston, how heavy a load can he lift with the jack?
Answer: 8.64 x 10³ N

A tank is filled with water to a height H, 28 m. A hole is punched in one of the
walls at a depth h, 7.84 m, below the water surface. What is the distance x
from the base of the tank to the point at which the resulting stream strikes the
floor? Could a hole be punched at another depth to produce a second stream
that would have the same range? If so, at what depth?
Answer: 25.1 m, 20.2 m, 14 m

The fresh water behind a reservoir dam is 15.0 m deep. A horizontal pipe 3.00
cm in diameter passes through the dam 7.5 m below the water surface. A plug
secures the pipe opening. Find the magnitude of the frictional force between
the plug and the pipe wall. What volume of water flows out of the pipe in 5.0
hours once the plug is removed?
Answer: 51.9 N, 154 m³

An airtight container having a lid with negligible mass and an area of 97 cm²
is partially evacuated. If a 717.80 N force is required to pull the lid off the
container and the atmospheric pressure is 1.0 × 10⁵ Pa, what is the air
pressure in the container before it is opened?
Answer: 2.6 × 10⁴ Pa

Forces F1, F2, and F3 act on a structure. To put the structure in equilibrium,
a force Fh and Fv are applied at a point located a distance d from F1. Given a
= 2.1 m, b = 3.1 m, C = 1.25 m, F1 = 22.05 N, F2 = 9.50 N, and F3 = 6.05 N,
find Fh, Fv, and d.
Answer: Fh = 6.05 N, Fv = 31.6 N, d = 1.34 m

A 1.11 × 10² kg crate is being pushed across a horizontal floor by a force P
that makes an angle of 32.1° below the horizontal. The coefficient of kinetic
friction is 0.223. What should be the magnitude of P, so that the net work

, done by it and the kinetic frictional force is zero?
Answer: 333 N

A fighter jet is launched from an aircraft carrier with the help of its engines
and a steam-powered catapult. The thrust of its engines is 2.48 × 10⁵ N. It
moves through a distance of 90.0 m and has a kinetic energy of 4.31 × 10⁷ J at
lift-off. What is the work done on the jet by the catapult?
Answer: 2.08 × 10⁷ J

A motorcycle (mass = 2.47 × 10² kg) is traveling at a steady speed of 21.4 m/s.
The force of air resistance acting on it is 1.80 × 10² N. Find the power
necessary to sustain this speed if the road is level.
Answer: 3.85 × 10³ W

A fireworks rocket is moving at 45.1 m/s. It breaks into two equal mass pieces
with velocities v1 at an angle of 31.5° and v2 at an angle of 58.5°. What is the
magnitude of v1?
Answer: 76.9 m/s

A ball of mass 0.30 kg is fired with velocity 160 m/s into the barrel of a spring
gun of mass 2.1 kg, initially at rest on a frictionless surface. The ball sticks in
the barrel at the point of maximum spring compression. What fraction of the
ball's initial kinetic energy is stored in the spring?
Answer: 0.875

A mine car (mass = 458 kg) is moving at 0.516 m/s on a horizontal track. A
chunk of coal (mass = 149 kg) is moving at 0.791 m/s and lands in the car.
What is the velocity of the car/coal system after the coal comes to rest in the
car?
Answer: 0.562 m/s

A 326-g stationary air-track glider is attached to a spring with spring constant
k = 5.82 N/m. A 163-g glider moving at 1.27 m/s collides elastically with the
stationary glider. How far does the spring compress?
Answer: 0.2 m

A 1100-kg car collides with a 1200-kg car that was initially at rest. After the
collision, the lighter car moves at 25.0 km/h at 20° with respect to the x-axis.
The heavier car moves at 28 km/h at -44° with respect to the x-axis. What was
