The potential energy at the end of the loop is equal to 0.3407 Joules.
<u>Given the following data:</u>
- Mass of rock = 102.16 g to kg = 0.10216 kilogram.
- Height of the loop = 34 cm to m = 0.34 meter.
- Acceleration due to gravity = 9.8
<h3>What is potential energy?</h3>
Potential energy (P.E) refers to the energy that is possessed by an object due to its position (height) above planet Earth.
Mathematically, potential energy (P.E) is given by this formula;
<u>Where:</u>
- m is the mass of an object.
- g is the acceleration due to gravity.
- h is the height of an object.
Substituting the given parameters into the formula, we have;
P.E = 0.3407 Joules.
<h3>What is kinetic energy?</h3>
Kinetic energy (K.E) refers to an energy that is possessed by a physical object due to its motion.
Mathematically, kinetic energy (K.E) is given by this formula;
<u>Note:</u> You'll have to calculate the velocity from the distance traveled by the car and photogate time in your experiment.
Based on the law of conservation of energy, we can deduce the following points:
- Potential energy (P.E) is <u>highest</u> at the top of the loop while kinetic energy (K.E) is <u>lowest</u>.
- Kinetic energy (K.E) is <u>highest</u> underneath the loop while potential energy (P.E) is <u>lowest</u>.

Answer:
(a)If two objects collide and one is initially at rest, is it possible for both to be at rest after the collision?
No. Because if you have initial momentum P⃗ ≠0 , if both of the objects were at rest after the collision the total momentum of the system would be P⃗ =0 , which violates conservation of momentum
(b)Is it possible for only one to be at rest after the collision?
Yes, that is perfectly possible. It characteristically, happens when both objects are of the same mass. When two objects of the same mass collide and Kinetic energy is conserved (Perfectly Elastic collision) then the two objects interchange velocities.
Answer:
Explanation:
We are asked to find the cyclist's initial velocity. We are given the acceleration, final velocity, and time, so we will use the following kinematic equation.
The cyclist is acceleration at 1.2 meters per second squared. After 10 seconds, the velocity is 16 meters per second.
= 16 m/s - a= 1.2 m/s²
- t= 10 s
Substitute the values into the formula.
Multiply.
We are solving for the initial velocity, so we must isolate the variable 
. Subtract 12 meters per second from both sides of the equation.
The cyclist's initial velocity is <u>4 meters per second.</u>
Answer:
"Cannot be determined," if that's an answer choice. It depends on the velocities of both objects, since momentum=mass*velocity.
