2023 HESI A2 PHYSICS EXAM PREP Q&A1. QUESTION Suppose the final velocity of a motorcycle is 26 m/s east, and it has an average velocity of 76 m/s east. What is the initial velocity of the motorcycle? Assume that the east direction is the positive direction of motion. o -152 m/s o 126 m/s o -126 m/s o 152 m/s We know the average velocity is half the sum of the initial and final velocities. However, this question asks us for the initial velocity. Step 1: Rearrange the average velocity fo...

PHSCS 121 Final Exam Questions with Correct Answers a driver who is protected by an air bag during a head-on collision is less likely to be seriously injured than an unprotected driver. this is because the airbag - Answer-increases the time interval over which the impulse is experienced 9cm a bullet moving horizontally strikes and sticks in a block of wood that is free to move on the horizontal, level, frictionless surface. the block has a much greater mass than the bullet. what become...

1d collisions head on collisions sticking together ANSWER : mv - mv = collective mass x v 1d collisions in the same direction not sticking together ANSWER : mv + mv = mv + mv 1d collisions in the same direction sticking together ANSWER : mv + mv = collective mass x v 1d explosions ANSWER : mv + 0 = collective mass x v 1d recoil ANSWER : 0 = mv + mv Gun velocity will be negative as it is going back 2d collisions ANSWER : Total momentum in vertical component Total momentum in ho...

Towards the end of a game, a team's pitcher begins to lose his focus and shortens his stride, uncoupling the kinetic chain at his hips. How will this impact his pitch? (A) It will make his shoulder more injury-prone as a result of the increased energy being dissipated during the follow-through from the inefficient kinetic chain. (B) It will decrease the velocity of the pitch due to a decrease in energy transfer through the torso (C) It will decrease the velocity of the pitch as a result of...

A 12-year-old male jumped approximately 12 feet from a tree and landed on his feet. He complains of pain to his lower back. What injury mechanism is MOST likely responsible for his back pain? Select one: A. Lateral impact to the spine B. Secondary fall after the initial impact C. Direct trauma to the spinal column D. Energy transmission to the spine (Ans- D. Energy transmission to the spine A 15-year-old female was struck by a small car while riding her bicycle. She was wearing a helme...

Abduction - Movement of the limbs away from the midline of the body. Acceleration - The rate of change in velocity. Acceleration (m/s//s) = (final velocity - initial velocity)/time. Actin-Myosin Filaments - Proteins which form the contractile units of skeletal muscle. Action Potential - Positive electrical charge inside the nerve and muscle cells which conducts the nerve impulses down the neuron and into the muscle fibre. Active Recovery - Low-intensity activity post exercise to maintain e...
