Transverse and longitudinal
Eddie walked to the physics club's pizza party and ate all the pizzas. When asked why he ate all the pizzas, Eddie answered: "I was just making up for the energy I lost walking up to our meeting room". What type of energy is present in Eddie's body during his walk? (Give three answers)?
mechanical energy, electrical energy, thermal energy, chemical energy

Calculate the efficiency of a rope-pulley system if a crane uses 2.47 kJ of mechanical energy to pull a 20.0 kg timber block 9.0 m off the ground.
71%
At what speed does electromagnetic waves move?
3 x 108 m/s
Eddie failed his physics test because he wrote: "Einstein won his first Nobel Prize for developing the theory of relativity". For what discovery did Albert Einstein actually win his first Nobel prize?
The photoelectric effect
Eddie launched Ritz's gaming laptop at an angle of 45° forward, with an initial velocity of 20 m/s. Air resistance is negligible, and g = 10 m/s2. Ritz placed a cushion 40 m away from the launch position, in an attempt to save his laptop. Will Ritz be successful? (Assume the cushion could absorb all the impact)
Yes
Eddie lost a game of CSGO. He punched his laptop with a force that is one fourth of his body weight and broke the laptop. If the maximum force the laptop can endure is exactly 200 N, and g is 10 m/s2, what is the minimum body mass of Eddie?
80 kg
Andi and a girl are pushing each other, both with wheels on their shoes. After the push, Andi is moving towards the right at 5 m/s. Andi’s mass is 70 kg, the girl’s mass is 50 kg. What is the girl’s velocity towards the left? Assume no friction.
5.92 m/s
A denser medium gives you a faster/slower sound wave. Answer with either "faster" or "slower".
Slower
Which physicist is more famous for his cat than for his equation?
Erwin Schrodinger
Andi is running at a constant velocity of 1 m/s. He sees a pretty girl passing by and starts accelerating constantly to catch up. After 3 seconds he reaches his maximum velocity of 7 m/s. How far does he run in the 3 seconds?
12 m
Block A (75 kg) and Block B (110 kg) are side-by-side on a horizontal surface with a coefficient of kinetic friction of 0.15. If a 730 N force is applied on the 75 kg block, calculate the force that each crate exerts on the other.
440 N
Eddie was frustrated that he failed his physics test. He dropped a rock from the top of a bridge (free fall). When the rock is halfway down to the river, its speed is what fraction of its final speed when it hits the water? Air resistance is negligible. Give your answer in decimal.
0.707
A guitar string vibrates at 294Hz. If the guitarist accidentally cuts the guitar string to ⅔ of its original length, determine the new frequency.
441 Hz
What is Dr. Dykshoorn’s PhD thesis about?
Quantum Field Theory
Andi wrote a love letter for the girl on a piece of paper. He rubbed the paper into a ball so that he could throw it to the girl. The girl is 20 meters away and Andi can throw the ball at an initial velocity of 15 m/s. What is the angle of elevation that Andi needs to aim so that the girl receives Andi’s love. Give all answers possible. No air resistance obviously.
30.35, 59.65
Andi is doing push-ups in an elevator so that he can flex his muscles to the girl. The elevator is accelerating towards the GROUND at 1 m/s2. Andi’s mass is 70 kg. How much force does his right arm have to exert on the ground of the elevator?
616.7 N
Harry is on the roof of a skyscraper and drops a 0.125 kg book over the edge. Andi, on the 8th floor, saw the book go by at a speed of 33.1 m/s. The first floor of this building is 12.0 m high, and each successive floor is 8.0 m high. How many floors does the building have?
15
Eddie was frustrated that he failed his physics test again. He shouted at an organ pipe that's closed at one end and has a length of 68 cm. If the speed of sound through the air inside is 340 m/s, what is the pipe's fundamental frequency?
125 Hz
