<p> Determining Speed, Velocity & Acceleration Name: ______Date: ______Pd. ______</p><p>Speed is a measure of how fast an object is moving or traveling. Velocity is a measure of how fast an object is moving or traveling in a certain direction. Both speed and velocity include the distance traveled compared to the amount of time taken to cover this distance. Acceleration means a change in speed or direction. It can also be defined as a change in velocity per unit of time.</p><p>Speed = distance velocity = distance (in a specific direction) acceleration = V f – V i time time time</p><p>Calculate the answers to the following questions. Show all of your work. Include the formula, input the variables, solve and box your answer. Speed 1. What is the velocity of a car that traveled a total of 75 Km north in 1.5 hours?</p><p>2. What is the velocity of a plane that traveled 3,000 miles from New York to California in 5.0 hours?</p><p>3. John took 45 minutes to bike to his grandmother’s house, a total of 4 km. What was his velocity in km/hr? In meters/ hour?</p><p>4. It took 3.5 hours for a train to travel the distance between two cities at a velocity of 120 mi/hour. How many miles lie between the two cities? What is this distance in km? ( 1 km = 0.62 miles)</p><p>5. How long would it take for a car to travel a distance of 200 km if it is traveling at a velocity of 55 km/hr? </p><p>6. A car is traveling at 100 km/hr. How many hours will it take to cover a distance of 750 km?</p><p>7. A plane traveled for about 2.5 hours at a velocity of 1200 km/hr. What distance did it travel?</p><p>8. A girl peddling her bike at a velocity of 0.10 km/min. How far will she travel in 2 hours?</p><p>9. An ant carries food at a speed of 1 cm/sec. How long will it take the ant to carry a cookie crumb from the kitchen table to the ant hill, a distance of 50m? Express your answer in seconds, minutes and hours.</p><p>10. The water in the Buffalo River flows at an average speed of 5 km/hr. If you and a friend decide to canoe down the river a distance of 16 km, how many hours and minutes will it take? Acceleration 11. A rocket traveling at 400m/sec fires its booster rockets until the craft reaches 550 m/sec. If the boosters fire for 30 seconds, what was the acceleration of the rocket?</p><p>12. After applying its brakes, a car accelerates at a rate of -15m/sec/sec. If the car was traveling at a rate of 25 m/sec, how long will it take the car to stop?</p><p>13. What will be the final velocity of a boat leaving the dock at the Philadelphia Naval Station at .5m/sec/sec if it travels for 2 minutes?</p><p>14. A ball rolls down a ramp for 15 seconds. If the initial velocity of the ball was .8m/sec and the final velocity was 7m/sec, what was the acceleration of the ball?</p><p>15. A spacecraft reaches a speed of 250m/sec in 10 seconds after an acceleration of 15m/sec/sec occurs. What was the original velocity of the craft?</p><p>16. In 0.5 seconds, a bullet goes from 0 to 300 m/sec. What is the acceleration of the bullet? </p><p>17. A rocket changed velocity from 1.0 km/sec to 1.8 km/sec in .03 seconds. What is the acceleration of the rocket?</p><p>18. The space shuttle releases a space telescope into orbit around the Earth. The telescope goes from being stationary to traveling at a speed of 1700m/s in 25 seconds. What is the acceleration of the satellite?</p>
