1 and 2 D motion, vectors, and Graphical analysis 1. A vector or a scalar quantity - make a table - mass, speed, displacement, velocity, distance, acceleration, temperature, time, force, energy, power, work, momentum, impulse, voltage, current, resistance. 2. Give the SI units for: distance, velocity, acceleration, force, work, energy, power, momentum, current, resistance, voltage, charge, time, frequency, wavelength, index of refraction, theta, magnification, and mass. 3. Using other SI units, give alternative ways to write the following units: Newtons, watt, ampere, joule, voltage, hertz, and acceleration (Example: 1 watt = 1 1/s) 4. A car increases its speed from 9.6 meters per second to 11.2 meters per second in 4.0 seconds. What is the average acceleration of the car during this 4.0-second interval? 5. How far will a brick, starting from rest, fall freely in 3.0 seconds? 6. A physics student drops a water balloon from a window that is 12m from the ground. How long does It take for the balloon to hit the ground? 7. A rock is thrown horizontally at a velocity of 12 m/s from the top of a cliff 68m high. How long does it take the rock to reach the bottom of the cliff? How far from the base of the cliff does it land?8. A roller coaster, traveling with an initial speed of 15 meters per second, decelerates uniformly at -7.0 m/s2 to a full stop. How far does the roller coaster travel during its deceleration? 9. A car starts from rest and accelerates at 2m/s27 How long does it take to move a distance of 5m? 10. What is the speed at the end of 320 m stretch if starts from rest and has an acceleration of 2m/s?? 11. If a ball is thrown with an initial horizontal velocity of 2.3m/s, from a tall building, a. how far away from the building does the ball land if it takes 4s to land? b. how tall is the building? 12. Sketch a graph of the velocity over time of an object that is thrown vertically and allowed to fall back to its original height, where t=0 s is the moment the ball leaves the hand. 13. A ball which starts at rest initially falls 80 m to the ground from the top of a building. a. Determine the time it takes to hit the ground. b. Determine the velocity of the ball as it hits the ground. c. Sketch a graph of the position of the ball over time and a graph of the velocity of the ball over time. 14. What is the Initial velocity required to vertically launch an object 45 m in the air
