In a physics lab experiment, a compressed spring launches a 30 gmetal ball at a 25 ∘ angle. Compressing the spring 19 cm causes the ball to hit the floor 1.7 m below the point at which it leaves the spring after traveling 6.0 m horizontally.
What is the spring constant?

In a physics lab experiment, a compressed spring launches a 36 g
metal ball at a 35 ∘ angle. Compressing the spring 20 cm causes the
ball to hit the floor 2.0 m below the point at which it leaves the
spring after traveling 5.9 m horizontally. Part A What is the
spring constant? Express your answer to two significant figures and
include the appropriate units.

1. A spring (k = 30 N/m) is compressed 5 cm and launches a 50 g
toy straight up. How high does the toy fly?
2. Two blocks are attached together with a piece of string.
Block #1 (3 kg) slides along a rough incline of 30º and block #2 (2
kg) hangs off the end of the incline. If the blocks accelerate at
4.5 m/s2 in the directions shown, determine the tension
in the string and the coefficient of...

As part of an experiment in physics lab, small metal ball of
radius r = 2.3 cm rolls without slipping down a ramp and around a
loop-the-loop of radius R = 3.4 m. The ball is solid with a uniform
density and a mass M = 373 g.
How high above the top of the loop must it be released in order
that the ball just makes it around the loop?
Now instead of a sphere, what if we rolled...

In a physics lab students are conducting an experiment to learn
about the heat capacity of different materials. The first group is
instructed to add 1.5-g copper pellets at a temperature of 92°C to
345 g of water at 16°C. A second group is given the same number of
1.5-g pellets as the first group, but these are now aluminum
pellets. Assume that no heat is lost to or gained from the
surroundings for either group.
(a) If the final...

In our physics lab, we did a experiment regarding Hooke's law,
and the goal is to find the spring constant by using a simulation.
In the first section of the procedure, our instructor intentionally
give us the wrong instruction, which tells us to find spring
constant using varying mass, delta x and constant gravity. In the
second section of the procedure, we need to figure out what went
wrong in the first section that caused us to incorrectly measure
the...

A
cannon directed straight upward launches a ball with an initial
speed v. The ball reaches a maximum height h in a time t. Then, the
same cannon is used to launch a second ball straight upward at a
speed 2v. In terms of h and t, what is the maximum height the
second ball reaches and how long does it take to reach that height?
Ignore any effects of air resistance.

A spring was compressed by varying load from 100N to 350N. If
the spring material is music wire, design the spring specifications
and indicate its factor of safety against fluctuating
stresses.Assume and state relevant parameters.

The figure shows an 8.5 kg stone at rest on a spring. The spring
is compressed 11 cm by the stone. (a) What is the spring constant?
(b) The stone is pushed down an additional 32 cm and released.What
is the elastic potential energy of the compressed spring just
before that release? (c) What is the change in the gravitational
potential energy of the stone–Earth system when the stone moves
from the release point to its maximum height? (d) What...

a 100 kg student is compressed 50 cm on a spring with a spring
constant of k = 80,000 N/m. He is on top of a 10 m frictionless
hill. He then is released from rest. He goes down to the bottom of
the hill before sliding up a 30° frictionless hill. a. (8 pts) Find
the speed of the student when he reaches the bottom of the hill. b.
(9 pts) Find the distance D the student travels up...
